4 CHAPTER 2. ABOUT CIA
2.2 System requirements
The CIA system requires the following resources:
• IDL must be installed on your system. Versions earlier than IDL 5.0 are not supported
by CIA 4.0.
• CIA needs disk space of 375 MB. Additional disk space of 450 MB is required for the
optional theoretical PSFs (available from the CIA server).
• Users should have access to 250 MB of swap space, bigger data-sets might require up to
1GB of swap space.
• CIA is supported to run on a Sun Sparc Solaris 2.5 (or later) and VMS Alpha 6.2 (or
later), and is known to run on DEC ALPHA OSF1 (Digital Unix), HP/UX (Hewlett-
Packard Unix) and x86 Debian Linux 2.0. Users are invited to build the CIA executables
and modify IDL coded modules so as to enable CIA to run on alternative platforms.
2.3 Getting started
Before proceeding make sure that CIA is properly installed on your system and that your system
meets the necessary requirement’s for running CIA (see Section 2.2).
2.3.1 How to Start CIA
This section is by its nature dependent on system configuration which can vary. In case of
problems consult your system manager, though Section 2.3.4 describes CIA customization and
may provide pertinent information on.
On VMS:
$ idl
If this fails try typing idl5.
On Unix:
> cia [version]
Here there is an optional parameter ‘version’ in the form MMMYY (eg APR00). The default will
usually be the latest version.
2.3.2 Using the Online Help: ciainfo, cia html and cia help
The CIA help system uses the old style IDL help. This is invoked by entering widget olh on
the CIA command line. The alias ciainfo will also invoke widget olh, provided of course that
the alias list is compiled. . .
