Contents of Marc Buie's IDL library.

General purpose IDL functions and procedures.

For those of you accessing these routines from within SwRI/Boulder, you get access by adding /net/frakir/raid/buie/idl (do NOT prepend a + to this directory) to your $IDL_PATH environment variable in your .userrc file. These routines are a collection of general purpose IDL functions and procedures covering diverse uses from file reading, astronomical data processing, and more. You must also have the Astronomy Users Library in your path to get full access. Here at SwRI, add +/net/frakir/idl/Astron to your path (before my library) to gain access.

You can download your own copies of my routines. The documentation on these WWW pages is kept consistent with the current version of my software (see recent changes). There are older copies of my library which are a snapshot of the code at the time of major IDL releases.

I've also begun more extensive documentation on my ITOOL/CCDPHOT programs. Actually, I only end up adding to this when I get requests for clarifications on the program operation that aren't covered by what's written so far. For those of you writing code for my library, please adhere to my style guidelines.
