FIXAN:  Task to fix the Antenna (AN) extension of a uv file.

                                   'CENT' - make Earth centric
                                            from correct AN file

FIXAN
Type:  Task
Use:   FIXAN fixes the contents of an antenna file (extension
       file type 'AN') associated with an data set.
Adverbs:
  INNAME.....Image name (name).      Standard defaults.
  INCLASS....Image name (class).     Standard defaults.
  INSEQ......Image name (seq. #).    0 => highest.
  INDISK.....Disk drive # of image.  0 => any.
  INVERS.....AN file version # read  0 => highest
  OUTVERS....AN file output version number: **** 0 -> INVERS! ****
  OPTYPE.....'WRNG' convert to Earth centric (simply add the current
                    BX, BY, BZ to the input array center) assuming
                    that the file had a naive (and incorrect) geometry
             'CENT' convert to Earth centric assuming that the file
                    had the correct (rotated by local longitude)
                    geometry.
             'SURF' convert to surface centric correctly
