GIRAFFE Low Resolution grating settings

SETUPS DEFINITION AND RESOLUTION.

From P84 in ARGUS/GIRAFFE, the setting LR01 is available in VISITOR MODE ONLY due to the problem ofobtaining sufficient counts in blue attached flats. For Medusa and IFUall settings are available in service and visitor mode.

Low resolution mode 600 lines/mm, 34.0 blaze grating.
