This page is part of the ING manual INS-DAS-29
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.
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.
Scope of the system
"UltraDAS" describes a vertical slice of the observing system. The latter
includes all the hardware and software used to make and record observations;
UltraDAS is the sub-set concerned with driving detectors and recording
data on disc.
The system computer is the one
one which the user interfaces are run. The term "DAS" is used in this document
(and other UltraDAS documents) to mean the computer
that collects data from the CCDs and files it on disc.
A share of the system computer and the software on it.
The CCD controllers.
UltraDAS does not cover:
Control of telescope and instruments.
Data reduction systems.
Logging of observations.
Writing of FITS tapes.
