Intermediate IDL

Hi Brent, Martin, Xua, Scott and Horst. Thanks very much for your enthusiasm last week. I really enjoyed teaching the IDL course to such an eager bunch. The source code that we developed together is listed below. Alternatively, the entire lot can be downloaded as a single zip archive.

I strongly urge that you spend a few interspersed hours over the coming weeks writing some more IDL code from scratch. A good exercise might be to look at the GUI images shown in the training manual then code them up without reference to the source code. You can then compare your solution with those developed in the manual. If you have any questions, feel free to contact me at darran.edmundson@anu.edu.au.
