Task: gpaver
Purpose: Average (smooth) gain solutions.
Categories: calibration

        GpAver is a Miriad task to average (smooth) antenna gains.
        Currently only boxcar averaging is supported.

Key: vis
        The input visibility file, containing the gain file to average.

Key: interval
        The time averaging interval, in minutes. The default is 10 minutes.

Key: options
          vector  Do vector averaging of the gain amplitudes and
        	  phases. This is the default.
          scalar  Do scalar averaging of the gain amplitudes and vector
        	  averaging of the gain phases
