PRTAN: Task to print the Antenna (AN) extension of a uv file.
INNAME Image name (name)
INCLASS Image name (class)
INSEQ 0.0 9999.0 Image name (seq. #)
INDISK 0.0 9.0 Disk drive #
INVERS -5.0 46655.0 AN file ver. #
NPRINT -5.0 32767.0 No. records to print 0 => all
DOCRT -3.0 132.0 > 0 => use terminal instead
> 72 => terminal width
Printer disk file to save
DOBTWEEN -1.0 1.0 > 0 -> print relative antenna
Use: PRTAN prints on the line printer the antenna file (extension
file type 'AN') associated with an image.
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
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
DOBTWEEN...> 0 means for the task to print the antenna coordinates a
second time with the coordinates altered when the input
coordinates are wrt the Earth's center. For the EVLA,
the traditional array center (FILLM) is subtracted from
the Earth-centered antenna coordinates now used. For
other arrays, the the second display is with respect to
the average of the antenna coordinates in the file.
These surface-centric coordinates are rotated to be
relative to the longitude of the center.

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