This page is part of the ING manual INS-DAS-29 Operations manual for UltraDAS

Purpose of this document

The use of UltraDAS in routine operations is described. "Routine operations" includes observing and changes of instrument and detectors, but not development and installation of UltraDAS components nor the preparation and tuning of detectors. The information is intended for guest observers, staff astronomers, duty engineers and change-crew personnel.

This issue describes UltraDAS in observing-system s9.

Don't panic!

This is a technical manual, but most of it can be ignored or intuited for most of the time. If you are about to observe with UltraDAS, have a quick look at the observing section and be prepared to dip into the command dictionary for occasional details. You can ignore the rest.
