1. Data Systems Environment at SM4

2. Data Systems Team (DST) Software
Subsystems
OPUS data processing system
STSDAS calibration routines developed by SSG are incorporated into the OPUS data processing pipelines.
DADS (Data Archive and Distribution System)
StarView archive interface
OTFR (On-The-Fly Reprocessing) system has components from OPUS, DADS, and StarView.
DST software is designed, as much as possible, to isolate the instrument/mission specific code.
This presentation describes general system enhancements for OPUS and DADS that will be applied to WFC3 data processing and archiving.

3. Anticipated changes to operational environment
All OPUS/OTFR, DADS ingest, and DADS distribution processes running on Tru64 UNIX cluster.
TruCluster software distributes processing load
No VMS/UNIX cross mounted disks
DADS interface with jukeboxes (NSA, archive engine) running on Solaris UNIX
Large disk cache to hold pod files for quick retrieval to OTFR

4. Initial Science Data Receipt

5. OPUS Science Data Processing

6. OPUS Engineering Data Processing
Receive engineering telemetry data from CCS at GSFC
Process Engineering data through FGS Data Pipeline
Generate data products to characterize jitter and pointing control information in support of science observations
WFC3 jitter file association packaging will mimic science data associations
No WFC3 specific requirements for jitter files
WFC3 specific ‘save files’ for ESS/ET will be generated
