Here we describe briefly a sample session with CHAMELEON. We include tips on how to get organized during the data reduction, as this is a time consuming process. We also assume that you are reducing output from CONSTRICTOR. (When re-calibrating data however, you will usually begin by reading the output of CHAMELEON.) After starting OYSTER, type oyster at the IDL prompt. In general, we work our way from the top (FILE) to the bottom (CALIBRATE) in the displayed OYSTER main widget. Also note that button labels are all caps if they bring up another widget. All other buttons either open another button list (if an arrow is displayed), or immediately execute the associated procedure.
