Special Seminar by Kostas Title: IDL Advanced Tutorial Abstract: This talk is aimed at a much more advanced level than the beginners tutorial I ran 2 weeks ago; it will be heavily related to plotting and input/output issues. As a modelE user I'll use its output for examples, but in a very generic way that can be applied to virtually any data processing. All IDL users are encouraged to attend. If you are working with modelE's tracers and using IDL, try not to miss it.
