SET Y

        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 visi-
        bility  in  the  subband(s),  sideband(s),  baseline(s)  (or  anten-
        na(s))  selected  by SET SUBBANDS, SET BANDS, SET  BASELINES or  SET
        ANTENNAS  commands.   Only  correlation  scans will be plotted,  not
        autocorrelations.

      AUTOCORR.    :    the  autocorrelation  power  measured  in   the sub-
        band(s),  antenna(s)  selected  by  SET  SUBBANDS,  and  SET  ANTEN-
        NAS  commands.  Only autocorrelation scans will be plotted, (includ-
        ing calibration 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  co-
        ordinates,  in  the (U,V) plane, of the baseline(s) selected by com-
        mand SET BASELINES.

      ATM_POWER: This is the output of the atmospheric monitor (normally the

    The  available  parameters  are the same as with the SET Y command.  De-
    fault is SET Y AMPLITUDE PHASE.

    The /LIMITS option is used to specify fixed limits, e.g.: "SET Y  AMPLI-
    TUDE  /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).
