SET ANTENNAS

            CLIC\SET ANTENNAS [a1 a2 ...]
            CLIC\SET ANTENNAS [ALL] [PHYSICAL]|[LOGICAL]

        Selects  the  antennas for which data will be displayed by command PLOT.
        This command is exclusive with commands SET BASELINES and SET TRIANGLES.

        Parameters which may be displayed in this antenna-mode are  obvious  an-
        tenna-based parameters such as cable phase, LO-phase and rate, ...  With
        SET Y AMPLITUDE and when more than 3 antennas are available in the data,
        antenna  amplitude is computed by averaging all possible "triangular ra-
        tios" of baseline amplitudes. With SET Y PHASE a phase is attributed  to
        each  antenna  by setting the phase of antenna 1 to zero, and making use
        of closure relations for other antennas (least square fit). This is use-
        ful  for fitting baselines for instance (it enables one to determine di-
        rectly antenna position offsets).

        SET ANTENNA with no arguments selects all antennas present in the  base-
        lines  previously  in  use. SET ANTENNA ALL will select all the antennas
        available in the first scan of the current index, for each  command  ac-
        cessing the data (e.g. PLOT).  This is the default.

        Note  that SET ANTENNA also allows to select the antenna to be processed
        by the SOLVE HOLOGRAPHY command (if several antennas are  selected,  the
        first one in the list is processed).

        SET ANTENNA PHYSICAL|LOGICAL allows to select if the antenna numbers are
        to be interpreted as physical (i.e. antenna ID) or logical (rank of  the
        antenna  in the ordered list of antenna physical number available in the
        observation). The antenna numbering in the header of boxes in  the  PLOT
        will change according to this switch.
