SET Y

 

        CLIC\SET Y parameter [/LIMITS]

    Choose the parameter to be plotted along y-axes by command PLOT.

    The  available  parameters  are  the  same  as  with  SET  X  parameter.
    Parameters valid in both TIME mode and SPECTRAL mode:
      AMPLITUDE,   PHASE,   REAL,   or   IMAGINARY:    referring   to    the
        visibility   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 autocorrelations.

      AUTOCORR.    :    the   autocorrelation   power   measured   in    the
        subband(s),   antenna(s)   selected   by   SET   SUBBANDS,  and  SET
        ANTENNAS commands.  Only  autocorrelation  scans  will  be  plotted,
        (including 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
        frequency if the velocity is correct.

    Parameters valid in TIME mode only:

      U_COORD, V_COORD, RADIUS, ANGLE:  referring  to  cartesian,  or  polar
        coordinates,  in  the  (U,V)  plane,  of the baseline(s) selected by
        command SET BASELINES.

      TIME: universal time (in hours, origin determined by  the  first  plot
        made, may be reset by PLOT /RESET).

        computed during the data compression.

        for baseline 12), or for the specified antenna(s).

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

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

        and the meridian plane)

        measured with given antenna).

      ATM_EMISSION: From the output of the atmospheric monitor (normally the

        atmosphere,  in  Kelvins  of  Rayleigh-Jeans  equivalent   radiation
        temperature.

      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
        during observations.


      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

        ambient load, and the equivalent temperature of the cold load.

    Default are :  SET Y AMPLITUDE PHASE.

    The /LIMITS option is used to specify fixed limits:

    CLIC\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 *  -180  180
    if  SET  PHASE  JUMPY  is  effective,  and  0 * * * if SET PHASE DEGREES
    CONTINUOUS ; with corresponding values if SET PHASE RADIANS).
