<task type="function" name="gaincal" category="calibration">
<shortdescription>Determine temporal gains from calibrator observations</shortdescription>
The complex gains for each antenna/spwid are determined from the
data column (raw data), divided by the model column, for the
specified fields. The gains can be obtained for a
specified solution interval for each spectral window, or by a spline
fit to all spectral windows simultaneously.
Previous calibrations (egs. bandpass) should be applied on the fly.
