Task: gpedit
Purpose: Edit the gain table.
Categories: calibration

        Gpedit is a MIRIAD task which modifies a gain table.

Key: vis
        The input visibility file, containing the gain file to modify.
        No default.

Key: gain
        Antenna gain to be used for the antennas affected. Given
        as amplitude (sqrt(Jy/K), and phase (degrees). Default=1,0.

Key: ants
        The antennas affected. The default is all antennas.

Key: feeds
        The polarisation feeds affected (e.g. R, L, X or Y). Default is
        all feeds.

Key: options
       This gives extra processing options. Several values can be given
       (though many values are mutually exclusive), separated by commas.
       Option values can be abbreviated to uniqueness.
       Possible options are:
         multiply  The existing gains are multiplied by the complex gain.
                    i.e. the amplitude is multiplied and the phase added.
         replace   The existing gains are replaced by the complex gain
        	    This is the default option.
         flag	    The existing gains are flagged as bad.

        Example:
          gpedit vis=cyga gain=14.4,90 ants=1,2 feeds=X
