Control of the medium resolution gratings is not yet supported by Remark. Users should refer to Message #40 in the apo35-dis mailing list for information on setting the desired grating tilt. The DIS software (mirella) has been updated by Robert Lupton to allow for the medium resolution gratings. This will be implemented when an updated version of Remark is available. It's incompatible with the current version, 2.39. I believe Bob Loewenstein is working on a new version at this time. - Karen G.
