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 meth-
    od).

    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).
