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 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-
      tions.

    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.

    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
      SET BASELINES.

      ture.

  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).
