Gain Calibration

General gain and bandpass calibration

In general, gain calibration includes solving for time- and frequency-dependent multiplicative calibration factors, usually in an antenna-based manner. CASA supports a range of options.

Note that polarization calibration is described in detail in a different section.

Frequency-dependent calibration: bandpass

Frequency-dependent calibration is discussed in the general task documentaion for bandpass.

Gain calibration: gaincal

Gain calibration is discussed in the general task documentation for gaincal.

Flux density scale calibration: fluxscale

Flux density scale calibration is discussed in the general task documentation for fluxscale.

Baseline-based (non-closing) calibration: blcal

Non-closing baseline-based calibration is disussed in the general task documentation for blcal.
