Follow these steps to reconfigure a grating if the graphical tool fails:
This document describes how to reconfigure a grating if the graphical tool and the script both fail.
A word on g#map parameters; the "coll angle" is really attached to the grating position, not the grating itself. In truth there are two values, a large correction for the grating position, and a smaller correction for the specific grating, but these numbers have not all been measured, and hence when in doubt you should use the coll angle shown below for that position (not for that grating)! However, the point of having the graphical interface is to avoid having to know these details, and have the computer do all of the work for you. We will update various parameters as they become known to us.
