CASB Report December, 2001

 

Highlights for Division Meeting

·         Completed construction of an astrometric mask from the POSS Quick V plate solution residuals.

 

Community Affairs and Communications

·         Several CASB members plan to attend the 199th AAS Meeting in Washington, January 6-10.

·         R. White and V. Laidler prepared a poster for presentation at the January AAS Meeting: "GSC2.2 vs SDSS EDR: Astrometry, Photometry, and Classification."

 

Project Management and Technical Infrastructure

·         Antonio Volpicelli started comparison of Objectivity and MS SQLserver for GALEX/GSC-II

·         McLean and Greene continued supporting SDSS planning activities.

 

MISSION SUPPORT

HST Operations

·         Reviewed 7 new Guide Star Problem Reports (GSPRs) this period.  Three of these were fine lock failures.  The other GSPRs documented the following failures: coarse track failure because the GS was fainter than the FGS threshold; search failure because the GS was a misclassified galaxy; two other GSs that were blends of wide pairs, causing acquisition problems.  Filed a Bad GS Alert for each of the GSs.

·         Continued planning to port the GetImage software to the Windows NT server.

·         Obtaining statistics from the log files concerning how often the webserver has been visited and, more specifically, how often the new GSC2 is being accessed. 

·         Occasionally answering questions from the APT team about the Bright Object Tool.

·         Draft HUGS2 report distributed for comments.

 

NGST Development Studies

 

                                      DIGITIZED SKY SURVEY

 

Plate Scanning

·         Scanning UKST-IR plates from the current ROE shipment.

 

GAMMA Microdensitometer Systems

·         In early December GAMMA2 developed a problem with shearing between forward and reverse sweeps.  Attempted to correct the problem, but have not succeeded.  Performed no production scans on GAMMA2 throughout most of the period.

·         GAMMA1 scans are marginally within tolerances.

 

Data Compression/CD Production

·         Continued compressing scans of the POSSII-N and UKST-IR surveys.

 

Archive Maintenance

·         Completed migration of the 1st 500 CDROMs in the jukebox to the RaidTec NFS raidarray. All of the images of the DQVS & DSS1 surveys have been migrated as well as the first 359 volumes of the XDSS red surveys. This represents about 300 GB of data.

·         A new load of 500 CDROMs is being readied for loading in the jukebox to continue copying.

·         Worked on two archive help desk requests for help/information.

·         Continued low-level rationalization of MOD archive.

 

 

GSC-II

 

Plate Processing and COMPASS Database

·         Continued processing POSS Quick V plates.

·         Completed construction of an astrometric mask from the POSS-I Quick V plate solution residuals.

 

CALIBRATIONS: General

 

CALIBRATIONS: Astrometry

 
CALIBRATIONS: Classification

 

CALIBRATIONS: Photometry (GSPC-II and DSS-I and -II)

·         J. Garcia completed the December CTIO 0.9 m observing run.
