SET GAIN_METHOD

        CLIC\SET GAIN_METHOD OLD|NEW

    Selects  the  method used to compute antenna-based gains from baselines-
    based measured  quantities.  Default  is  OLD  (older  but  more  robust
    method).

    OLD  method: 'gain' for a antenna i is computed from three baselines (Gi
    = Gij.Gik/Gjk). All possible "triangular ratios" including the antenna i
    are  computed  and averaged (for the phase, only triangles including the
    reference antenna are considered).

    NEW method: 'ALMA' like method. Solves the linear  system  of  equations
    (for the amplitudes, solves the logarithms).
