CORRECTIONS

                  OBS\CORRECTIONS Caz Cel [Focus] [/ANTENNA Iant]

         Enters pointing corrections and the focus zero  for  antenna  Iant.
    Caz  and  Cel  are  offsets  from  respectively -COH and -COV, the radio
    collimations, while Focus is an offset from HFO0 the nomi focus.   Using
    *  instead of a numerical value means do not change this parameter.  Caz
    and  Cel  are  in  arcseconds,  while  Focus  is  in  millimeters.    In
    single-dish mode, Iant defaults to the single-dish antenna


    Command CORRECTIONS is intended to be used for temporary  changes  only,
    for  example  to  help  in  a pointing session, or to refine the current
    pointing on a particular source.   Corrections  are  remembered  by  OBS
    using  the  MEMORY.OBS procedure, and NOT reset to 0 by a SET\OBSERVE or
    SET\POINTING command.  To  change  permanent  pointing  parameters,  the
    SET\POINTING  command is recommended, and corrections should normally be
    set to zero.
