HELP SECTION
FITOUT
Type: Adverb (String*48)
Use: To specify the name of some disk file outside the usual AIPS
catalog system to be used as output from an AIPS verb or task.
The file is a text file giving the results of a fitting process.
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,
FITOUT = '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:
FITOUT = '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
FITOUT = '/home/primate2/egreisen/AIPS/Text.prt
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.
In some programs, it is regarded as an error if FITOUT already
exists. Most concatenate to or replace pre-existing FITOUTs.
All tasks below concatenate to the output file.
Null value: ' '
Taken to mean no subsidiary file. This can be an error.
