caltabconvert – Convert old-style caltables into new-style caltables. – utility task

Description

This task converts old-style (up to CASA 3.3.0) caltables into new-style (CASA 3.4.0 and later) caltables. It is provided as a convenience and is strictly temporary. The information transferred should be enough for most calibration purposes. BPOLY and GSPLINE versions are not supported. Only simple bugs will be fixed. If there are other issues, it is suggested that a new-style caltable be created directly.

Parameter Explanations

caltabold

vis

''

Name of the visibility file (MS) associated with the old-style caltable.

ptype

'complex'

Type of data in the new-format caltable.

Default: “complex” Options: “complex” or “float”

Note: The old-style caltables do not have this information, so it is imperative that users get it correct. “complex” refers to caltables that have complex gains (e.g., produced by gaincal, bpcal, etc.). “float” refers to caltables that real numbers such as delays (e.g., produced by gencal).

caltabnew
