SET SUBBANDS

        CLIC\SET SUBBANDS n1 n2 ...  [/WINDOW f1 l1 f2 l2 ...]
        CLIC\SET SUBBANDS ALL
        CLIC\SET SUBBANDS EACH
        CLIC\SET SUBBANDS LINE|CONT

    Selects  the  subbands for which data will be displayed by command PLOT.
    Valid codes are continuum subbands numbers (C01, C02, ...  C08) or  line
    subbands  numbers (L01, L02, ... L08). These are logical numbers, so one
    should select e.g. L01 to L04 if four correlator units were used,  inde-
    pendentely  from  the  physical units actually used. This is a classical
    trap: if e.g. units 1 to 5 were used on Receiver 1 and units 6 to  8  on
    Receiver  2,  the  corresponding subbands will be L01 to L05 for the Re-
    ceiver 1 scan, and L01 to L03 for the Receiver 2 scan.

    Subbands may be grouped by typing e.g. "SET SUBBANDS n1  to  n2  and  n3
    n4".  Here,  two quantities will be plotted. The first one is either the
    average of subbands n1 to n2 and n3 (in time mode), or the concatenation
    of  spectral  data from subbands n1 to n2 and n3 (in spectral mode). The
    second quantity plotted is subband n4.

    SET SUBBANDS ALL will automatically select all the subbands in the first
    scan of the current index, for each command accessing the data. The sub-
    band are concatenated (equivalent to e.g.  SET SUBBANDS L01 to L06).

    SET SUBBANDS EACH will automatically select  all  the  subbands  in  the
    first  scan  of  the current index, for each command accessing the data.
    The subband are NOT concatenated (equivalent to e.g.  SET  SUBBANDS  L01
    L02 L03 L04 L05 L06).

    SET  SUBBANDS LINE|CONT will switch all subbands to their line/continuum
    counterpart, e.g. L01 to L04 will be changed to C01 to C04 by SET  SUBB-
    BANDS CONT. Done by SET X I_F

    CLIC\SET SUBBANDS n1 n2 ...  /WINDOW first1 last1 first2 last2 ...

        The /WINDOW option select the first and last channels to be used for
        the LINE subbands. There should be one couple of parameter for  each
        group of subbands.

        In spectral mode, the window limits may be used to restrict the plot
        to a certain range, e.g.
            SET SUBBANDS L01 TO L02 /WINDOW 10 64

            will avoid plotting channels 1 to 9 of each of the two  subbands
        L01 and L02 (which are here combined to a single spectrum). This may
        be useful to flag meaningless channels at the low-frequency  and  at
        the  high  frequency ends of each spectral correlator. Note: this is
        now done automatically, see SET DROP command.

        In time mode, the window limits select the data to be integrated  to
        compute a single point.For example
            SET SUBBANDS L01 L02 /WINDOW 1 10 1 10 will plot data integrated
        from the first ten channels of the first line subband,  as  a  first
        quantity, and data integrated from the first 10 channels of the sec-
        ond line subband, as a second quantity.

        Note:  if you want to use both continuum and line subbands,  in  the
        same  plot   page, you should include dummy arguments in the /WINDOW
        option for the continuum spectra:
            SET SUBBANDS C01 to C10 L01 to L02 /WINDOW 0 0 2 64  (two  argu-
        ments are needed for each resulting spectrum).
