<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. The gains can be
obtained for a specified solution interval, spw combination and field
combination. The GSPLINE spline (smooth) option is still under
Previous calibrations (egs, bandpass, opacity, parallactic angle) can
be applied on the fly. At present with dual-polarized data, both
polarizations must be unflagged for any solution to be obtained.
