CASB Report April 2003

 

Highlights for Division Meeting

·         None

 

Community Affairs and Communications

·         McLean visited OATo April 22-30 for GSC-2 management meeting

·         Conducted several tours of Plate Vault and Scanning facilities

·         Planning visits to STScI by Drimmel (June), Lattanzi/Bucciarelli (July/August) and Spagna/Carollo (September/October)

 

Project Management and Technical Infrastructure

·         Due to insufficient EMC disk space for image archive migration, we are investigating alternative with CPT

·         Received another request to scan “staff research plates” – this is in support of an approved HST cycle 12 program.  On hold till after survey plates completed.

 

MISSION SUPPORT

HST Operations

·         Investigated 18 bad guide star alerts. Continued to develop software to update the keywords of the header files.

·         GSC2 Query code with ra,dec limits delivered to ESS for integration into NGSS

 
NVO Development Studies

·         See NVO report

 
NGST Development Studies

 

                                      DIGITIZED SKY SURVEY

Plate Scanning

·         The LAST UKSTU N plates were finally received and scanned.

·         Continued scanning the POSS-I O (blue) survey plates.

 
GAMMA Microdensitometer Systems

·         GAMMA1 replacement A/D converter has received. Downtime expected to be another 4-6 weeks. Scanning continuing on GAMMA2.

 
Data Compression/CD Production

 

GSC-II

COMPASS Database

·         Latest version of GSPC2 loaded into database
·         As of 31-March-2003 the COMPASS database contained 2,205,362,290 unique object index entries.  At this time, 6361 GSC2 plates are loaded and 6129 GSC2 plates are matched.

 

Plate Processing

 

Calibrations

·         Relatively high object matching failure rate with new version of GSPC2 is under investigation.

·         Loomis and Carollo observed with the La Palma JKT telescope for GSPC2 (Apr 4-13)

·         Garcia observed with ESO telescope at CTIO for GSCP2 (Apr 3-5)

·         Initial proper motion tests were completed by OATo. It appears that the currently implemented technique provide sufficient precision to support HST operations. It has been decided to defer an implementation of the more accurate technique to a future release.
