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.
