AIPS HELP file for OUT2CLAS in 31DEC22
As of Tue Feb 7 13:34:23 2023
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

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
VTESS.........Deconvolves sets of images by the Maximum Entropy Method.
The second output is the convolved version of the first
