CASB Report October 2002

 

Highlights for Division Meeting

·         Provided NVO Simple Image Access services for DSS archive in support of science demos.

 

Community Affairs and Communications

·         Ricky Smart announced the birth of his daughter, Arcadia Rebbeca Smart, on 5 Oct 2002. He reports that the world is a smarter place.

·         Conrad Sturch is retiring in November. 

·         Supported several tours of the plate vault and scanning facilities.

 

Project Management and Technical Infrastructure

·         Final agreement reached between ODM and ESS on staff assignments.

·         Wil O’Mullane concluded a working visit to develop web services for CASB archive data.

 

MISSION SUPPORT

HST Operations

·         Investigated 5 bad guide star alerts.  All turned out to be unresolved (on the Schmidt Plate) multiple star systems, classified in GSC1 as single stellar objects.  The much higher angular resolution of the HST FGS is able to separate the closely spaced systems. Filed a Bad GS Alert for each of the GSs.

·         Continued to update the keywords of the header files.

 

NVO Development Studies

·         Provided NVO Simple Image Access services for DSS archive in support of science demos.

·         Developed and delivered capability for VOTable loading with selectable color table viewing of morphological parameters into Aladdin visualization tools.

·         Coordination with JHU and STScI in support of cluster morphology demonstration is ongoing to develop an NVO portal service to integrate services.

·         SOAP web service was built for HST cone search.

 
NGST Development Studies

·         No activity

 

                                      DIGITIZED SKY SURVEY

 

Plate Scanning

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

 
GAMMA Microdensitometer Systems

·         Gamma 1 suffered a mechanical failure and will require some maintenance work.  This work is expected to be simple and routine, barring any unforeseen problems.

·         GAMMA2 continues to operate smoothly. 

 

Data Compression/CD Production

·         Solved the problem of writing CDs using PC software on plextor.  In the revised procedure, the old premastering software is still run; the resulting img file is copied to plextor and then renamed to be an iso file, which the PC software can handle. 

·         Expect to clear the backlog of CDs by the end of the month.

·         Starting to investigate reported problems with reading data in 5 different DSS regions.

·         Investigating how to copy data from the MOD archive to the new spinning disk array that may be available soon.  Studying how to mount this disk such that the VMS produced data is viewable from UNIX.

·         Replied to one helpdesk request for support.

 

 

GSC-II

 

Plate Processing and COMPASS Database

·         As of 29-Oct-2002 the COMPASS database contained 1,042,955,086 unique object index entries.  At this time 5757 GSC2 plates are loaded and 5211 GSC2 plates are matched.
·         The database file system has grown to 1.91 TB in size and is currently at 62 % of the total            hard disk capacity of the current RAID array.

·         Unmatched and deleted a small number of plates from the database in order to reprocess and recalibrate some older POSS 1 data.   All plate material (POSS1, POSS2 and quick V) in a small area surrounding the northern galactic pole was recalibrated loaded and matched for a test of the proper motion algorithm. 

·         Continue to work through all the problem plates for both the northern and southern IVN surveys.  This activity was given slightly higher priority during the previous several weeks, in order to achieve completion of loading and matching of the IR survey material.

·         Most of the available POSSI-O plate scans have been processed

·         Completed final testing of a program that will access the current GSC2 database and obtain information needed to create MCO files for calibration purposes.

·         Created a PERL script that will automatically run the createMCO application using the GSPC2 and Tycho2 catalogs given an input list of desired MCO files.

·         Continuing port of the object classifier application from VMS to Windows 2000.

 

Calibrations: Astrometry

·         NGP POSS-I plates were reprocessed, loaded and matched in the database.  Computed the proper motions for these regions and delivered the data to OATo for analysis.

 

Calibrations: Classification 

·         Continuing port of the object classifier application from VMS to Windows 2000.

 

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

·         Loomis spent 7 nights observing at the Observatorio del Roque de Los Muchachos on the Island of La Palma in the Canary Islands.   The observing was hampered somewhat by the weather, but a number of previously unobserved GSPC2 fields were observed. 

·         Data was taken on every night and several of the nights offered excellent observing conditions while weather and dust reduced the observing efficiency on other nights.  Part of one night was devoted to a target of opportunity override request for astrometry of a near Earth object.   The data are being reduced.

  • S1. Low priority program to rescan crowded fields (|b|<30) originally done with 25 mu scans.  The total number of S scans includes the 2 for the LMC and SMC plus 4 others with |b|>30 performed for research or STIS BOP support.  Another 30 plates have been added to replace those that were repaired before inclusion in DSS-I.
  • S2. This survey is an on-going low level-of-effort collaboration between the STScI and the AAO.
  • S3. Low priority scans of the POSS-I -24 deg and -30 deg zones.
  • S4. Includes recent scans of better grade plates.
  • S5.  Low priority scans of the moderately short exposure R plates from the SERC I/SR Atlas of the Milky Way.
  • S6.  Includes UKST-IR plates from the SERC I/SR Atlas of the Milky Way and the Magellanic Clouds (1978-1985) and the I-Survey of the Southern Sky (1990-xx).
  • S7. IR plates taken with the UK Schmidt to complete the POSSII-N Survey.
