Changes

The 2D window shows two horizontal cyan lines which should coincide with the upper and lower bounds of the spectrum. These have been manually set for each grating and show the bounds over which analysis will take place. For example, side bands for sky subtraction are truncated at these edges. If these are not in the appropriate place, they may be tuned by editing a configuration file as described herehttps://topswiki.saao.ac.za/index.php/Quick_Look_Tool#Edges_of_2D_spectrum . These bounds are also used to define where an arc is extracted ZZZ(see end of section below).
