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 subbands 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  interval
  before  processing,  to  improve  the signal-to-noise ratio.  Default is 4
  seconds.

  The presence of option /PRINT produces a procedure file  (INTER_OBS:point-
  ing.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 giv-
  en.  The file is given extension .lis by default; a new file is opened ex-
  cept  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 argument FLUX
  changes the output format for the determination of relative fluxes (by AS-
  TRO). With argument TPOINT, the output is written in a format 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 parame-
  ter. 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 POINTING
  /TOTAL /COMPRESS /PLOT /FIX ZERO 0).
