SET ANTENNAS

 

        CLIC\SET ANTENNAS [a1 a2 ...]
        CLIC\SET ANTENNAS ALL

    Selects the antennas for which data will be displayed by  command  PLOT.
    Valid  antennas  are  currently  1, 2, and 3.  This command is exclusive
    with commands SET BASELINES and SET TRIANGLES.  Parameters which may  be
    displayed in this antenna-mode are obvious antenna 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  ratios"  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
    useful for fitting  baselines  for   instance   (it   enables   one   to
    determine directly antenna position offsets).

    SET ANTENNA with no other antenna selects  all  antennas  used  for  the
    baselines previously in use.

    SET ANTENNA ALL will select all the antennas available in the first scan
    of  the  current index, for each command accessing the data (e.g. PLOT).
    This is now the default.
