AIPS HELP file for CALIN in 31DEC18
As of Wed Apr 25 15:46:07 2018
Type: Adverb (String*48)
Use: To specify the name of a disk file outside the usual AIPS
catalog system to be used as input for an AIPS verb or task.
The file is usually calibration information.
Format: The name is usually given by specifying a logical device plus
directory, followed by a colon, followed by the actual file
name. In Unix, logicals are environment variables. The
logical name must be set up before entering the AIPS program
and is usually in upper case. Thus, for example:
percent setenv MYAREA ~joeuser
for the C shell, and
$ myarea=$HOME; export MYAREA
for bourne, korn, and bash shells. Then in AIPS,
CALIN = 'MYAREA:FITS.DAT'
Note that the Unix-standard $ ahead of the logical is omitted.
AIPS-standard logicals like FITS (often AIPS/FITS) are available
also. Other forms are now acceptable as well:
CALIN = 'FITS.DAT
will find the file in the $FITS directory (when reading or
writing FITS disk files) or in the directory local when you
started AIPS. A full path name may also be given
CALIN = '/home/primate2/egreisen/AIPS/N6503.fits
if it fits in 48 characters. Note that the trailing quote mark
is left off and this is the last command on the input line so
that the case is preserved.
Under UNIX, it is now possible to read and write tape files with
other, cooperating computers. If the other computer is running
the AIPS "deamon" task TPMON, then INFILE may also take the form
where is the name of the other computer, and is
a name known to TPMON on that computer. This limitation
probably requires you to use the $FITS or $RUNFIL or other
widely known AIPS areas. (For real tape, the node name is given
in the MOUNT command instead.) This option only applies to tapes
Null value: ' '
Taken to mean no subsidiary file. This can be an error.
For tapes, it means use a real tape drive given by INTAPE
(which must already be MOUNTed).
