What is IDL?
On the odd chance the reader is an astronomer who does not know what
IDL is, it is the Interactive Data Language. This is a commercial
package sold by RSI. It was built to do
data reduction and analysis in an interactive way, but with enough
functionality to write scripts to automate the process. Personally,
the author dislikes it (having once called the bastard child of
FORTRAN and C shell) but it works well at what does, which is fast
numerical calculations in a complete environment.
What do I need to use IDL? Option 1
One of the most useful, basic set of packages is the IDL Astronomy
User's Library. This has been around since the last millenium, and
it contains useful tools for reading and writing FITS files,
including tables, math, statistics, plotting, photometry, image
display, coordinate transformations, etc.
If you get the Princeton tools below, you do not need this package.
What do I need to use IDL? Option 2
There is a set of useful routines developed at Princeton as part of
the SDSS spectroscopic pipeline, which includes the GSFC IDL
Astronomy User's Library. These are used by the DEEP2 pipeline and
by XIDL. These routines and the help pages discussing them, where
written assuming that you would be using their software. Below I
link to the webpage that describes how to install the packages and
setup your IDL to find them. There are similar discussions in the
DEEP2 and XIDL pipeline web pages.

Gosh, wouldn't it be nice if I could just get everything at once?
If you act now, you can!
Below are precompiled versions of the
IDL routines and the XIDL and DEEP packages. They exist for IDL 6.3
on Intel Macs. One version is for the Xeon architecture, and one
version is for the older Intels. You can find out which version you
want by clicking About This Mac. If it says Xeon, get the Xeon
version. Both are compiled under Leopard.
Note: both include a .idlenv file for path information!
Note: both include all of the calibration files required for DEIMOS and HiRes.
