Changes
/* Grating angle change instructions with the temporary brake in place */
- They will adjust the angle until they are happy with the set of arc lines landing on the CCD
- Enable the physical brake on the grating (inside the instrument) by tightening the 4 black bolts
- Tighten the bolts '''''carefully''''' to avoid disrupting the grating (one could slightly change the angle and the process will need to be repeated)
- Take an arc to make sure that the lines did not move significantly
- Once the desired angle has been set and the arc still looks good, click ''Apply Grating Brake'' in the ''Config'' tab
