Recipes for IDL

IDL, Interactive Data Language, is a 1970s programming language for image analysis.  It remains expensive and gets replaced by Python.  Traditionally, IDL was popular in astronomy and medical imaging.  In solar physics the large SolarSoft library requires IDL until portage to Python is complete.

If you want to use IDL programs from my libraries download the zip collection, unzip, and include rjr.lib in your IDL search path.
