Calibration table conventions

The calibration table definition is available in AIPS++ Note 240. Calibration tables are always cumulative for the specific Jones type they contain. Thus they always refer to the observed DATA column as corrected by Jones matrices of other types. Thus, only one calibration table of each type may be applied to correct the data. Provision for incrementally refining the calibration of a specific Jones type, as in self-calibration, is available.

The calibration tables are not attached to a given MS, but contain references to the MS with which they are associated. Thus they can hold calibration solutions from a collection of different measurement sets, as the capability is provided to append to an existing calibration table. The calibration tables are defined by user-specified text names, which are entirely under user control.
