1.6.3.3 Gain Calibration

The gaincal task determines solutions for the time-based complex antenna gains, for each spectral window, from the specified calibration sources. A solution interval may be specified. The default ’G’ solution mode solves for antenna-based gains in each polarization in specified time solution intervals. The ’T’ solution mode is the same as ’G’ except that it solves for a single solution shared by both polarizations.

A spline fit for the solution (solution type ’GSPLINE’) may be carried out instead of the default time-slot based ’G’ solutions.

See § 4.4.3 for more on gain calibration.
