CLIC\SET Y param1 [param2 ...] [/LIMITS min1 max1 [min2 max2 ...]]
Choose the parameter to be plotted along Y-axes by command PLOT.
Parameters valid in both TIME mode and SPECTRAL mode:
AMPLITUDE, PHASE, REAL, or IMAGINARY: referring to the visibil-
ity in the subband(s), sideband(s), baseline(s) (or antenna(s))
selected by SET SUBBANDS, SET BANDS, SET BASELINES or SET ANTENNAS
commands. Only correlation scans will be plotted, not autocorrela-
AUTOCORR. : the autocorrelation power measured in the sub-
band(s), antenna(s) selected by SET SUBBANDS, and SET ANTENNAS
commands. Only autocorrelation scans will be plotted, (including cal-
ibration scans), not correlations.
Parameters valid in SPECTRAL mode only:
CHANNEL : channel number in the correlator (use ony this one if
Fourier Transform has not been made).
VELOCITY : normally with respect to LSR.
I_FREQUENCY : the frequency in the second IF (around 350 MHz).
SKY_FREQUENCY : the sky frequency. This should be the line rest fre-
quency if the velocity is correct.
Parameters valid in TIME mode only:
U_COORD, V_COORD, RADIUS, ANGLE: referring to cartesian, or polar coor-
dinates, in the (U,V) plane, of the baseline(s) selected by command
TIME: universal time (in hours, origin determined by the first plot
made, may be reset by PLOT /RESET).

RMS_PHASE: the r.m.s. of the phase of the average of the non-
flagged subbands of the continuum correlator, in current phase
units (degrees or radians). This r.m.s. phase is computed
during the data compression.
RMS_AMPLITUDE: the r.m.s. of the amplitude of the average of the
non-flagged subbands of the continuum correlator, in current am-
plitude units (kelvins or janskys). This r.m.s. amplitude is
computed during the data compression.
DELAY: as specified for specified baseline (differential, A1-A2
for baseline 12), or for the specified antenna(s).
LO_RATE: as specified for specified baseline (differential, as DELAY),
or for the specified antenna(s).

or for the specified antenna(s).

LAY), or for the specified antenna(s).

TOTAL_POWER: the total power measured for the given anten-
na(s), as measured by the connected detectors.
LAMBDA, BETA, or FOCUS: the scanning coordinates for pointing and fo-
cussing scans (arc seconds, or millimeters), for the specified an-
tenna, or the moving antenna if the given baseline (if only one is
AZ_CORR: the azimuth collimation correction in arc seconds.
EL_CORR: the elevation collimation correction in arc seconds.
FOC_CORR: the Z focus correction in millimeters.
T00 ... T04 : general test parameters (in data headers)
T10 ... T14 : test parameters (antenna based) (in data headers)
TREC: receiver temperature for the given antenna(s).

rical mean of Tsys for both antennas), or for the given antenna(s).
PAMB, TAMB, HUMIDITY: measured atmospheric parameters.

ages and maxima..

AZ_ERR, EL_ERR: The tracking errors in arc seconds.
AZ_PH, EL_PH: The azimuth and elevation for each record (as used for
PARAL_ANGLE: Parallactic angle (angle between the vertical direction and
the meridian plane)
WATER: Water content of atmosphere (as set by the programmer, or mea-
sured with given antenna).
ATM_EMISSION: From the output of the atmospheric monitor (normally the
1.3mm receiver). This is the measured radiation temperature of the at-
mosphere, in Kelvins of Rayleigh-Jeans equivalent radiation tempera-
ATM_POWER: This is the output of the atmospheric monitor (normally the
1.3mm receiver). It is the actual counts that appear on the monitors
ATM_REFERENCE: The atmospheric emission used as a reference for the
phase correction. This is computed by the command MONITOR. The phase
correction will be proportional to the difference between the output
of the atmospheric monitor and this reference value.
ATM_PHASE: The computed atmospheric phase correction.
ATM_UNCORRPH: The phase uncorrected from atmosphere.
ATM_CORRPH: The phase corrected from atmosphere.
ATM_VALIDITY: 0 or 1 whether the phase correction has been declared
valid or not.

The available parameters are the same as with the SET Y command. Default
is SET Y AMPLITUDE PHASE.
The /LIMITS option is used to specify fixed limits, e.g.: "SET Y AMPLITUDE
/LIMITS a1 a2" where a1 and a2 are the amplitude limits to be used in this
example. The codes "*" and "=" may be used. "*" means that the limits are
automatically adjusted to the data, separately in each box; "=" means that
common limits to all boxes are computed.
Default limits are provided for AMPLITUDE and PHASE only: 0 * * * if SET
PHASE CONTINUOUS is effective, 0 * -180 180 if SET PHASE JUMPY DEGREE
(with corresponding values if SET PHASE RADIANS).
