February 10, 1995

The ST ScI's Observation Support System (OSS) and Post-Observation Data
Processing System (PODPS) teams are being merged. The new organization will
be called OPUS, the OSS-PODPS Unified System.

While the procedures to be followed by the OPUS team are still being developed
and will probably continue to be developed throughout 1995, a broad outline
of how existing services will change can be sketched. The new, more restricted
services were implemented on January 16, 1995.

Most of the services these two teams currently supply will continue, though
there may be some changes in how they are implemented.

1) Real-time commanding for interactive acquisitions and other required
uplinks identified in your proposals will continue with no change to
you, the observer.

If you request, OPUS team members will still handle the real-time
decision for you. As before, you will have to provide sufficient
information to them concerning the expected field.

2) Requests for unscheduled pointing corrections must be made at least
24 hours in advance of the observations (72 hours if the pointing
correction must be implemented after midnight and before 8 am). These
must be accompanied by a scientific justification. Requests are
evaluated for scientific impact, for feasibility and for effect
on current operations before they are approved.

3) You may inspect the observations on a quick look basis on the operations
computers if specifically requested in the proposal. Unless the proposal
logsheet specifies "RT analysis" or "INT ACQ", the observations will not
be available until after they enter the production pipeline. If your
proposal does not identify a quick look requirement, you still may request
quick look inspection of observations if you justify why you cannot wait
for access through the DADS and if the request is made at least a week
in advance.

If a spacecraft or instrument emergency is declared, quick look inspection
will be provided to the instrument scientists and engineers without prior
approval.

4) The OPUS team will continue to inspect observations and the concurrent
engineering data to determine whether there are anomalies with the
execution of the observations or with the performance of the instrument.
Deficiencies that might decrease the scientific utility of the data will
be documented in the PDQ files.

This inspection will occur after the concurrent engineering data
are received in the production pipeline. Typically the receipt of the
engineering data will be 24 to 48 hours after the observation occurs.

Real-time target acquisitions and unscheduled pointing corrections will
continue to be documented in the Observer's Comment files (OCX files).

5) You will still be notified of failed and missing observations though
notification will be less timely due to the delay in receiving the
engineering data.

6) "Fast track" transfer of science data is discouraged, but will still be
provided if sufficiently justified.

Observations will no longer be available routinely in near real-time
in the OPUS era. Generally science data will only be available after
it has entered the production pipeline. This typically occurs within
24 hours after they are transmitted from the HST.

Unless problems occur in the data calibration stage, the data are not
expected to be available for "fast track" much earlier than they are
transferred to the DADS archive system. Therefore, requests for the
"fast track" must justify why you cannot wait for access through the
DADS.


Several services will not be supported after the end of January.

1) OPUS will not have a store of near real-time engineering data for anomaly
investigation. Instrument engineers will take the lead in obtaining any
needed data from the ESS system at Goddard.

2) OPUS will not provide round the clock on-call support for science
instrument or spacecraft anomaly investigation.

3) OPUS will not have a capability to use unscheduled real-time commanding
for rescuing observations after a failed onboard target acquisition.
