Bringing up IRAF
Before running IRAF, there is a simple set-up procedure which
is computer- and operating
system-dependent. The necessary steps to obtain the correct set-up
for a SUN workstation
are listed below. Specific
instructions should be obtained by the user from local computer system
and IRAF managers.1
Tasks to be performed:
- 1.
- create a user directory from which IRAF will be run (called
`myiraf' in these examples). This will
contain the user set-up specifications and other IRAF-related
subdirectories.
- 2.
- create an image directory in a disk partition where there is enough
space to contain large files (image arrays). Usually this is
assigned by the system manager in
a scratch area, periodically cleaned by the system. Data files
should be kept in this image directory (imdir); the IRAF *.pix
files
are automatically stored in imdir.
- 3.
- move into the `myiraf'
subdirectory, and run the procedure mkiraf.
This creates a file (login.cl) which executes the set-up
each time a new IRAF session is started. mkiraf should be run
every time there is a new release of
IRAF.
An example execution of these tasks appears below.
To customize a few of the default options (e.g., type of editor,
default printer), the user has two options:
- edit the login.cl file. This requires editing and reassigning
user choices every time mkiraf is run since mkiraf initializes
login.cl at each execution of mkiraf.
- create a loginuser.cl file that contains user customizations. The
assignments in this file override those in login.cl. The file needs
to be changed only to reflect changes in the user choices.
IRAF can be run from any terminal. However, graphics or image display
capabilities require the appropriate hardware.
Throughout this document we use `visitor' as the username,
`/pool' as the scratch area, `/pool/visitor'
as the image directory (imdir) and `myiraf' as the sub-directory from which
IRAF will be run (home).
