Q4HEADER
Type: Verb
Use:  Q4HEADER lists header information from the catalog file selected
      by the 4th input file name adverbs.  It will list only the first
      image satisfying the selection criteria specified by the
      adverbs.  It lists only the most important parameters and shows
      the coordinate values at the center pixel.  IM4HEAD lists rather
      more parameters and shows the coordinate values at the reference
      pixel.
Adverbs:
  IN4NAME.....4th image name(name).       Standard defaults.
  IN4CLASS....4th image name(class).      Standard defaults.
  IN4SEQ......4th image name(seq.  #).    0 => highest.
  IN4DISK.....4th disk drive # of image.  0 => any.
