Common Astronomy Software Applications

CASA, the Common Astronomy Software Applications, is the primary data processing software for the Atacama Large Millimeter/submillimeter Array (ALMA) and Karl G. Jansky Very Large Array (VLA), and is often used also for other radio telescopes.

6.5.1 Release

CASA 6.5.1 can now be downloaded for general use. CASA 6.5.1 is available either as a downloadable tar-file, or through pip-wheel installation, which gives flexibility to integrate CASA into a customized Python environment.

CASA 6.5.1 includes bug fixes and updates to a few tool methods. Noteworthy is a fix to a bug in tclean, which prevented a proper use of the UV taper parameter with natural weighting in CASA 6.2 - 6.5.0.

For details on these and other new features, see the CASA 6.5.1 Release Notes.

CASA is developed by an international consortium of scientists based at the National Radio Astronomical Observatory (NRAO), the European Southern Observatory (ESO), the National Astronomical Observatory of Japan (NAOJ), the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA), CSIRO Astronomy and Space Science (CSIRO/CASS), and the Netherlands Institute for Radio Astronomy (ASTRON), under the guidance of NRAO.
