Space Telescope Science Institute Spectrographs Group Procedures
HOW TO INSTALL THE XSTIS IRAF PACKAGE:
Last Revised Dec 2010
The following are instructions for installing the xstis
package in IRAF. The xstis package consists of a group of
tasks used by the Spectrographs Group to test new or
modified scripts and code within the IRAF environment before
moving them to a standard package. After testing and
approval the task(s) will be moved to teststis for internal
use only tasks, or STSDAS for release to the GO community.
As these tasks are considered experimental, it is not
recommended that they be shared with General Observers.
To correctly install the XSTIS Package, and have access to
all the internal IRAF and IDT IDL Tasks, as well as to the
oref/ directory, do the following:
1. Edit the .envrc file in your home directory.
Comment out the IRAF line. Uncomment the IRAFX line, the
IDL entry, and add a line for the new STIS package. Things
should end up looking like this:
Note: People in a GO support position need to be able to
switch to public release IRAF at will so that they can
see the results as the GOs do (See Ed's unix/startup
.alias example for IRAF startup setup).
2. To have access to the internal xstis IRAF package, add
these lines to your login.cl or preferentially your
loginuser.cl file in your IRAF directory:
set xstis = "/grp/hst/stis/software/"
task xstis.pkg = xstis$xstis.cl
reset helpdb = (envget ("helpdb") // ",xstis$helpdb.mip")
4. Log out of your window manager and log back in.
5. Test the set up
a) Start up iraf
cl> show iraf
You should see
typing xstis at the cl> prompt will load the internal xstis
package. You can also cd to oref$ from within IRAF (reference
files directory) to verify that it is being correctly found.
