We assume you have sucessfully installed the ISAP code , copied some data into your data directory and have just typed " IDL ISAP_GUI_START". The guide is given in two formats. Firstly without pictures unless you explicitly look at them i.e I am assuming you are running this html session in parallel with your first idl session and you can see the real GUI yourself. The same information is then repeated with pictures. Finally a full listing of the buttons is given incase I have missed any.
The GUI Guide - no pictures (unless you really want them..)
The ISAP GUI Guide - with notes and pictures
Description of the Buttons - fairly random! .
