SOLVE POINTING

        CLIC\SOLVE POINTING [beam] [/PLOT] [/COMPRESS [timex]] [/PRINT]
        [/OUTPUT filename [NEW|APPEND] [FLUX] [TPOINT]]
        [/TOTAL] [/FIX param1 [value1] param2 [value2] ... ]

    Find pointing corrections from POINTING scans.  All  pointing  scans  in
    the  current  index  are  processed  by a gaussian fit. Its width can be
    fixed if the argument 'beam' is given (in arcsec).  All  continuum  sub-
    bands  and  both  side bands are averaged.  SET AVERAGE METHOD SCALAR is
    recommended. The fits may be displayed with option /PLOT.

    The option /COMPRESS may be used to average data in a given time  inter-
    val before processing, to improve the signal-to-noise ratio.  Default is
    4 seconds.

    The  presence  of  option  /PRINT  produces  a   procedure   file   (IN-
    TER_OBS:pointing.obs),  to  be  used  in  OBS for introducing the fitted
    pointing offset.

    The results may also be written on an output ASCII file  if  /OUTPUT  is
    given.   The  file  is  given  extension  .lis by default; a new file is
    opened except if APPEND is given as a second argument of option /OUTPUT.
    The  file  is by default in a format suitable for the determination of a
    pointing model (program POINT at BURE). The presence of  optional  argu-
    ment  FLUX  changes  the output format for the determination of relative
    fluxes (by ASTRO). With argument TPOINT, the output is written in a for-
    mat suitable for processing by the TPOINT program.

    ****** ATF CORNER ******

    With  option  /TOTAL,  SOLVE  POINTING uses the total power to solve for
    pointing errors. In that case, option /FIX may be used to fix one param-
    eter. Possible parameters are:

        AZ: the azimuth collimation error (arc sec.)
        EL: the elevation collimation error (arc sec.)
        PEAK: the peak amplitude, in total power units
        WIDTH: the HPBW (arc sec.)
        ZERO: the off-source zero level, in total power units

    With  /TOTAL, /COMPRESS does the ON-OFF combination if in beam switching
    mode. In that case ZERO is preferrably fixed to zero (e.g. SOLVE  POINT-
    ING /TOTAL /COMPRESS /PLOT /FIX ZERO 0).
