Main UVa IDL Site
- For a demonstration of IDL,
type idldemo at the UNIX command line
- The fastest way to learn to use IDL efficiently is to study
examples of user-written IDL programs. You can display on your screen
the code for any program (except for the proprietary built-in
routines) by typing .run -t [program
name]. If you want a copy of the program written to your
current directory, use the getpro
ATV Image Display Tool
- ATV is an IDL widgit-based display program
that behaves like DS9 and SAOimage
here). It was written by Aaron Barth. It's a quick and easy way
of inspecting 2-D data and doing rough analysis like plotting
image slices or getting FWHM's and brightnesses of sources. Oriented
toward CCD data.
- At UVa, ATV software is kept in /astro/idl/atv and is included by
default in your IDL path.

Help With IDL Programming and Routines
- ITTVIS supplies documentation, interactively linked to your
active session, with each IDL purchase. PDF versions of the latest
documentation can be found on the ITTVIS IDL
Product Documentation Page.
- To access the IDL manuals from the UNIX command line, type idlman or idlhelp.
- To access documentation for IDL_5.1 in HTML with a browser,
- To access hyper-help from within IDL, type ? or ?[topic].
Note: In some versions of IDL (e.g. v.6.0), the IDL
hyper-help system has been badly conceived.
You should upgrade if you find yourself
frustrated by older help facilities.
- Most non-proprietary routines, e.g. those in the Astronomy User's
Library, contain an internal documentation section written in a
standard format. This can be accessed by several different routines
within IDL, such as man. You can
obtain the relevant programs from Wayne Landsman's help
contrib library. Many non-proprietary routines are coded such
that if you simply type the name of the routine without arguments, it
will print the parameter sequence expected (no special access software
