HELP SECTION

PRTAN
Type:  Task
Use:   PRTAN prints on the line printer the antenna file (extension
       file type 'AN') associated with an image.
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 ver. #          0 => highest.
  NPRINT.....Number of antenna records to list,  0 => all.
  DOCRT......False (<= 0) use the line printer if OUTPRINT = ' '
                   else write named OUTPRINT file only.
                   When OUTPRINT is not blank, DOCRT=-2 suppresses the
                   page-feed character on page headers and DOCRT=-3
                   suppresses page headers and most other header
                   information.
             True  (> 0) use the terminal interactively.  The task will
                   use the actual terminal width as a display limit
                   unless 72 < DOCRT < width.  In that case, the display
                   limit will be DOCRT characters.
  OUTPRINT...Disk file name in which to save the line printer output.
             ' ' => use scratch and print immediately for interactive
             jobs - batch jobs use OUTPRINT = 'PRTFIL:BATCHjjj.nnn'
             (jjj= job #, nnn = user #).  When OUTPRINT is not blank,
             multiple outputs are concatenated, and the file is not
             actually printed.

EXPLAIN SECTION

PRTAN:  Task to print the Antenna (AN) ext. of a uv file.
Documentor: E.B.Fomalont
Related Programs: FITTP, IMHEADER, EXTLIST, EXTDES

                         PURPOSE

     PRTAN will list antenna parameters associated with a
uv-data base.  This file is an extension file of the type 'AN'.
If the u-v data is a concatenation of several data bases, there
will be many 'AN' file version, one for each of the original
data bases.

     The output consists of two parts.  First, the header of
about six lines lists the file name and general array parameters
such as polar motion parameters, clock offsets, earth rotation
rates, etc; most of which are VLB specific.  Then, parameters
associated with each antenna are listen.  For VLA observations
the useful data includes telescope number, station, baseline
parameters in meters.  Other information is VLB specific.

NPRINT
     NPRINT number of antennas will be listed.  If NPRINT=0, all
antennas will be listed.  Each 'AN' extension version must be
run separately.
