  • 06/15/23 CAS-13794 [6.5.6.16] - task_msuvbin: a new experimental task to save a measurement set as a UV grid. This can provide data compression in certain circumstances and is a prerequisite for a new flagging algorithm currently under development.  Images created from the gridded MS may differ significantly from those created from the original MS and differences will typically vary with changes to the gridding parameters. Users are cautioned to characterize these differences before including this experimental task in their scientific workflows.

  • 06/15/23 CAS-14043 - task_applycal:  the task will now handle calibration tables that have fewer SPWs than the MS they are being applied to.

  • 05/06/23 CAS-13899 [6.5.6.11] - The bug for cube with perchanweightdensity was because the the second psf making (with the offcenter  centering) did not get the perchan weightdensity initialization to do perchanweightdensity. That is fixed now and also a psf refitting is done once the psf is made and that solves the issue for mfs getting  a psf size that does not match what the psf looks like.

  • 05/04/23 CAS-14121 [6.5.6.10] - Fixed issue with image.summary() documentation.

  • 05/03/23 CAS-14073 [6.5.6.9] - Added a new table tool method tb.getcoliter() that provides iterator access to casacore tables.

  • 04/20/23 CAS-13827 [6.5.6.5] - Fixed bug in task imsmooth/tool method ia.convolve2d() in which the fitted beam was added to the output image metadata rather than the specified target beam in the case of targetres=True and the input image having a single beam. The fitted beam can vary from the target beam if the kernel is poorly sampled (ie there are too few pixels across the kernel). Warning messages are now emitted in the case where the kernel and target beam major or minor axes differ by more than 0.1%. In general, for a reliable solution, the kernel should be well sampled, so in the case where it is poorly sampled, either the target beam should be increased in size (so that the convolution kernel increases in size so that it is better sampled), or the input image should be regridded to have smaller pixels (again so that there are more pixels across the kernel so it is better sampled).

  • 04/17/23 CAS-13857 [6.5.6.4] - Infrastructure changes to create a more modular build system.  The new system uses standard tools to find the preinstalled dependencies. The C++ part and the python parts are now split: the C++ part uses modern cmake whereas the python part uses standard setuptools, compiling only the C++ swig interface and linking against the rest of casa C++ code as an external library.

  • 04/17/23 CAS-13857 [6.5.6.3] - Infrastructure changes to create a more modular build system.  The new system uses standard tools to find the preinstalled dependencies. The C++ part and the python parts are now split: the C++ part uses modern cmake whereas the python part uses standard setuptools, compiling only the C++ swig interface and linking against the rest of casa C++ code as an external library.

  • 04/13/23 CAS-14050 [6.5.6.2] - xml-casa: fixed a bug that disabled automatic parameter type coercion. This caused task_rmtables to iterate over each character when given a string instead of a list. Other cases such as the gaintable parameter of calibration tasks were similarly affected.

  • 04/06/23 CAS-13625 [6.5.6.1] - Updated ia.statistics() docs to describe the *force* parameter in a bit more detail.

  • 03/24/23 CAS-14038 [6.5.6.0, 6.5.5.19] - * Per-scan interpolation (i.e., interpolation that respects scan boundaries) has been implemented and can be used by adding 'perscan' to a particular interpolation method (e.g. 'linearperscan', cf 'linearperobs') or by using the 'scanmap' parameter when using the Cal Library syntax. This is supported in applycal (and apply by solve tasks) for all caltable types. * Correlations may now be combined for solving in the fringefit task via the corrcomb parameter * In fringefit, for solutions executed with combine='spw' (one solution from aggregation of many spws), the concatspws=True/False parameter toggles between simple aggregation on a global frequency grid before the FFT state (True, the default, and the existing default behavior in fringefit), and per-spw FFTs preceding summing in the transform domain using the shift theorem to ensure coherence (False). concatspws=False is an experimental mode for spw combinations which explores avenues for flexibility (spws on incongruent grids) and efficiency.

  • 03/24/23 CAS-14076 - Verification test development

  • 03/23/23 CAS-13191 [6.5.5.18] - task_tclean: fixed a crash when the observatory name was not recognized; fixed a bug when using awproject and wprojplanes=1 in parallel; resolved inconsistencies between using gridder=awproject in wproject-only mode and gridder=wproject; commissioned gridder=awproject for specmode=cube; makePB can now be called separately from makePSF.

  • 03/22/23 CAS-13973 [6.5.5.17] - Added ALMA-specific methods rxbands() and subwindows() to msmetadata tool. These methods return the receiver band(s) and spectral subwindow(s), respectively of the specified spws. If no spws are specified, then these methods return a list of values for all spectral windows. In cases where values cannot be determined, -1 is returned.

  • 03/15/23 CAS-13766 [6.5.5.16] - Added a check to catch an unreasonable input spectral index value.

  • 03/14/23 CAS-13889 [6.5.5.15] - plotms: plotms shall export the text data with a sufficient precision as followed, * velocity: 9 digits (at most, considering the precision of the light speed). * ant-Ra/ant-Dec, Az/EL, and ant-Az/ant-EL: at most 5 digits after the decimal point

Added a new option 'fullsummary' as a subparameter of niter != 0 that can be set to False to avoid issues with very large cubes. 

  • 01/18/23 CAS-13845 [6.5.3.25] - performance of imaging tasks, tsdimaging and tclean, was improved about 10-16%.

  • 01/06/23 CAS-13885 [6.5.3.24] - Documentation: added returns section to all tasks that return some result

  • 01/05/23 CAS-13997 [6.5.3.23] - task_tclean: fixed a bug that could cause FilebufIO and RegularFileIO exceptions to occur during the minor cycle.

  • 09/29/22 CAS-13920 [6.5.3.1] - task_tclean: peak memory and runtime profiling routines have been removed as they sometimes were the cause of a crash; the corresponding keys in the return dictionary will no longer be present.

  • 09/27/22 CAS-13877 [6.5.3.0, 6.5.2.25] - Infrastructure change to support the modular build system

  • 09/26/22 CAS-13856 [6.5.2.24] - Fixed plotms crash when combining antenna iteration, averaging and negation.

  • 09/21/22 CAS-13915 [6.5.2.23] -  Add a fallback method of using ssh when https is not permitted in test runner

  • 09/19/22 CAS-13910 [6.5.2.22] - The getWeather function of plotbandpass now uses np.median when combining values across multiple weather stations to prevent potential issues with faulty values.

  • 09/12/22 CAS-13194 [6.5.2.21] - Simulator tool : The Simulator code underlying sm.settrop() was improved by enabling the tool to support visibility integration times as short as 0.1 s . The new parameter "simint" (seconds) controls the time granularity of the simulation. Default value for simint is -1 which uses a granularity of 10 s (the same as in previous CASA versions).

  • 09/09/22 CAS-12555 [6.5.2.20] - task flagdata : The mode='shadow' now uses the uvw values found in the UVW column of the MS to calculate the uv distances of baselines, for all baselines for which such values are available. For baselines not present in the MS, shadow flags are derived by calculating UVW values from antenna positions.

  • 09/08/22 CAS-13842 [6.5.2.19] - Runtime performance of ephemeris imaging with tclean and tsdimaging was improved.

  • 09/07/22 CAS-13654 [6.5.2.18] - Updated imhead exception message in the case of mode='get' to alert the user that the expected values for hdkey in this case are often different from the keys in the dictionary returned by mode='summary'.

  • 09/06/22 CAS-10682 - Performances of task sdimaging have been improved, by caching spectra coordinates computed while creating the normal image and re-using - instead of re-computing - them when creating the weight image. A new parameter - enablecache - has been added to the task, making it possible to turn this new feature on or off. The performances improvement is most noticeable for fast-scan datasets with a few channels. For typical fast-scan solar datasets, re-using cached spectra coordinates is roughly 20 times faster than re-computing them, resulting in a 25~30% speed-up for the whole sdimaging task.    

  • 09/06/22 CAS-13917 [6.5.2.17] - Maintenance tasks for Bamboo automated tests.

  • 09/06/22 CAS-13144 - deconvolve : A new task named 'deconvolve' has been added to provide stand-alone access to the image-domain deconvolver algorithms available within tclean. Options supported in this initial version are 'hogbom','clark','clarkstokes','multiscale', with support for single-plane images and spectral cubes. The 'mtmfs' and 'asp' algorithms will be enabled in a later release.

  • 08/26/22 CAS-13867 [6.5.2.16] - None

  • 08/24/22 CAS-13739 [6.5.2.15] - tclean : Added a new iteration control parameter 'nmajor' to directly limit the number of minor-major cycle sets.

  • 08/23/22 CAS-11936 [6.5.2.14] - calanalysis module : Warnings appeared in the pipeline when a baseline was flagged completely. This was switched from a WARNING in the logs to an INFO post. task plotbandpass : Messages that earlier appeared only in the console, now appear in the logs of casa and the pipeline.

  • 08/22/22 CAS-13862 [6.5.2.13] - None

  • 08/12/22 CAS-13880 [6.5.2.10] - None

  • 08/11/22 CAS-13813 [6.5.2.9] - casalog tool : A new method, getOrigin() has been implemented to retrieve the origin of messages to be displayed.

  • 08/11/22 CAS-13820 - Update runtest testrunner to update xml to display results in bamboo. Display now shows testscript testclass.testcase in bamboo results page

  • 08/10/22 CAS-13631 [6.5.2.8] - (Needed for Oct 2022 ALMA pipeline deployment branch. Enables inclusion of self-calibration implementation in pipeline.) New task uvcontsub added for continuum subtraction in the uv-domain. The old task uvcontsub has been deprecated and renamed as uvcontsub_old. Task uvcontsub3 has been removed. The option douvcontsub of mstransform has been deprecated. (Note: suggested to highlight in the release notes that combine='spw' is future development)

  • 08/10/22 CAS-13861 - None

  • 08/08/22 CAS-13850 [6.5.2.7] - ImageAnalysis tool : (1) Added complete docs for image.beamarea(). No interface changes. (2) Added string mbret parameter to image.restoringbeam(). mbret="list" is the default, and produces backward compatible behavior. mbret="matrix" indicates that the return dictionary should be structured such that 'bmaj', 'bmin', and 'bpa' have numpy arrays as values, making it simple to utilize these values as numpy arrays rather than having to write python code to construct such structures.  

  • 08/08/22 CAS-13871 - Build System rework : Edited includes in some files.

  • 08/04/22 CAS-13860 [6.5.2.6] - None

  • 08/01/22 CAS-13858 - None

  • 07/28/22 CAS-13718 [6.5.2.3] - task_fringefit:  This task now supports the {{uvrange}} parameter provided through the {{selectdata}} facility. The documentation for this parameter can be found in the "Calibration Synthesis" section of the manual.  Users inexperienced with this parameter are warned that the uvrange selection is made _before _calibration; which data are calibrated and which are flagged may not match expectations unless the consequences of the selection are carefully thought through.

  • 07/25/22 CAS-13760 [6.5.2.2] - plotms : Fixed an int overflow bug that sometimes prevented interactive flagging/locating from working correctly.

  • 07/21/22 CAS-750 [6.5.2.1] - tool_table: Implemented more thorough input checking and better error handling in the getcellslice() method.

  • 07/20/22 CAS-13674 [6.5.2.0, 6.5.1.22] - task_sdbaseline: Fixed the output in ascii-text and csv formats in case of per-spectrum baseline fitting so that unnecessary info (non-existent parameter values) is not printed

  • 07/20/22 CAS-13673 - task_sdbaseline: Fixed the incorrect parameter names output in ascii-text format in case of per-spectrum baseline fitting

  • 07/19/22 CAS-13660 [6.5.1.21] - task_tclean: fixed a bug that prevented an outer UV taper to work in combination with weighting='natural'.

  • 07/19/22 CAS-13849 - tool_quanta: added a new parameter keepshape to qa.quantity and qa.unit to preserve the shape of N-dimensional arrays.  These N-dimensional quantities are compatible with qa.convert but not with other quanta tool methods.

  • 07/18/22 CAS-13808 [6.5.1.20] - tool_table: a new row() method and tablerow class was added to facilitate reading and writing of table rows.

  • 07/18/22 CAS-13869 - task_tclean: the warning for non-zero edge pixels in the PB image will now only be shown for gridders 'mosaic' and 'awproject'.

  • 07/15/22 CAS-12313 [6.5.1.19] - Correction to the inline docs of the sm.setnoise tool method.

  • 07/15/22 CAS-13668 - Fixed a bug found in sdbaseline when blmode=‘apply’ is selected. Now this setting properly takes account mask information and calculate weight correctly when baseline-subtraction is applied separately from the fitting.

  • 07/14/22 CAS-13785 - task_plotms: fixed a crash when turning calibration on without giving a cal library string.

  • 07/14/22 CAS-13738 [6.5.1.18] - * casashell now prints out a summary of any python exceptions that happen during startup (previously it would silently exit). Users of the monolithic CASA should not notice any changes. This change is primarily useful to developers building the components locally. * the setup.py build scripts now print out information about exceptions that happen during that process (previously they were largely silent). This change is only relevant to developers.

  • 07/12/22 CAS-13831 [6.5.1.17] - task_sdimaging: Fixed a caching issue that could lead to slightly different images from the same data selection.

  • 07/11/22 CAS-12901 [6.5.1.16] - task_plotms: the tick labels will now switch to scientific notation when displaying small values near zero or very large values

  • 07/06/22 CAS-13821 [6.5.1.14] - task_immoments: fixed a rare bug where writing history to the output files could cause a crash.

  • 07/03/22 CAS-13839 [6.5.1.13] - Updated ALMA Band 1 parameters in simulation tasks and tools.

  • 06/30/22 CAS-13855 [6.5.1.12] - replaced instances of numpy.asscalar with numpy.ndarray.item inside the test code of sdimaging

  • 06/29/22 CAS-13667 [6.5.1.11] - task_sdbaseline:  blmode=‘fit’ will now properly account for mask information and calculate the weight of the baseline-subtracted spectral data.

  • 06/28/22 CAS-13824 [6.5.1.10] - tool ms.getdata(): fixed a bug where averaging multiple columns could yield different results than averaging a single column
