HELP SECTION

OUT2CLAS
Type: Adverb  (String*12)
Use:  Data files are stored in AIPS under logical names which have 3
      parts: a 12-character "name" field, a 6-character "class" field,
      and a numeric "sequence number" field. OUT2CLAS is used to specify
      the "class" field for the secondary output data file from a verb
      or task.  This adverb is handled by AIPS tasks and verbs under
      special "wildcard" rules.  These rules determine how the default
      output class is combined with the user-specified OUTCLASS to
      create the class field actually used.  Except for '*', '?', and
      trailing blanks (when an * is present), all characters specified
      in OUT2CLAS are copied to the corresponding character positions in
      the final class field.  A '?' in OUT2CLAS causes the corresponding
      character in the default class to be used.  An '*' in OUTCLASS
      causes 0 or more characters (as many as possible) from the default
      class to be used beginning at the character position of the *.
      The number of characters (excluding trailing blanks) which follow
      the * in the user-specified OUT2CLAS determine how many characters
      may be used.  For the examples, assume that the default class is
      '123456'.  Then, OUT2CLAS = '*' results in an actual class of
      '123456'.  OUT2CLAS = 'A?B*D' results is 'A2B45D' and OUT2CLAS =
      '?? CAL' results in '12 CAL'.
Null value:  '      '
      Taken as '*' and the "default" value for OUT2CLAS is the task name
      unless the Help file for the specific task or verb states
      otherwise.  If the first character in OUT2CLAS is a back slash
      ('_'), then the default is changed from the task name to the
      actual INCLASS.  The _ does not appear in the final output class,
      but the remaining 5 letters (if any) in OUT2CLAS are used as above
      (as if they had been typed in character positions 1 - 5 of
      OUT2CLAS).

Tasks:
   HUINT.........Make RGB image from images of intensity & hue, like
                 TVHUEINT.  The second output is the wedge image.
   RFARS.........Correct Q/U cubes for Faraday rotation synthesis results.
                 The second output image if the imaginary part,
   SCIMG.........Full-featured imaging plus self-calibration loop with
                 editing.  The second output is the calibrated UV data.
   SCMAP.........Imaging plus self-calibration loop with editing.  The
                 second output is the calibrated UV data.
   TVHUI.........Make TV image from images of intensity, hue, saturation.
                 The second output is the wedge image.
   UTESS.........Deconvolves images by maximizing emptiness.  The second
                 output is the convolved version of the first output
                 image.
   VTESS.........Deconvolves sets of images by the Maximum Entropy Method.
                 The second output is the convolved version of the first
                 output image.
