CASB Report February
2002
· Achieved a high production rate this month for GSC2 processing of both the northern and southern infrared plates scans; over half are now processed.
·
Began database
loading of infrared plates.
·
· Volpicelli continued comparison of Objectivity and MS SQLserver for GALEX/GSC-II.
·
McLean and Greene continued supporting SDSS
planning activities.
·
Hiring of replacement software developer in
progress (offer made)
· Reviewed 13 new Guide Star Problem Reports (GSPRs) this period. Eleven of these were fine lock or reacquisition failures. One of the other GSPRs documented a GS that was fainter than expected. The remaining GS was a misclassified galaxy. Filed a Bad GS Alert for each of the GSs.
· Supported investigation of bright object protection for a STIS MAMMA imaging program in the extremely complex sky region of the SN1987A llght echo.
· To save disk space and with concurrence from the Science Planning and Scheduling Team, deleted all remaining confirmation charts for the still-active Cycle 9 SNAPs.
· Continued the port of GetImage to the Windows NT server.
· Continued to obtain statistics of webserver visits, specifically, accessing of GSC2.
· Occasionally answering questions from the APT team about the Bright Object Tool.
· Analyzing responses to the draft HUGS2 report.
·
Reviewing draft CSA FGS concept design
· Completed scanning UKST-IR plates from the current ROE shipment.
· Scanned the last two available POSSII-N plates from Palomar.
· Resumed scanning the POSS-I O survey on GAMMA1.
· GAMMA2 is still down; performed no production scans on GAMMA2 throughout the period.
·
Completed the
CD-ROM containing the compressed scans of the last four available POSS-II-N
plates.
·
Completed
migration of all available POSSII-N XDSS CDROMs to the RaidTec NFS raidarray.
·
A total
of 993 CDROMs with 645GB of compressed files has been transferred.
·
Started
migration of the UKST-IR XDSS CDROMs.
·
Worked
on two archive help desk requests for help/information.
·
Continued
low-level rationalization of MOD archive.
· Heavily concentrated resources on processing the infrared plate scans in both the north and south. Achieved a high production rate this month; over half of these plates are now processed.
· Rebuilt the LoadOOP database task. Updated the load and match daemon script to reflect the changes from the COMPASS upgrade. Started the load and match process and began ingest of infrared plates in both database loading and matching. Performed some minimal QA to ensure proper loading of these plates into COMPASS.
· Installed the CIQA tools on COMPASS for GSC2 QA.
· Investigated problems with GSC2 and CASB web services. Blocked an IP address that was accessing our web site and creating errors. The errors generated from this request overloaded our server and denied access to others.
· The IP address that was blocked originated from an anonymous Internet access provider. It is only a guess, but this incident appears to be another case of someone trying to download the entire unreleased GSC2.2.1 catalog.
· Obtained pre-release version of the Millennium Galaxy Catalog (Liske et al 2002). This catalog contains nearly 9000 hand-classified galaxies in the magnitude range 16 < B < 20, over an area near the north galactic pole that covers several GSC2 plates. This will be a terrific resource for analysis of the GSC2 classification at the faint end. A first look at the data matched to the uncut GSC2.2.1 indicates ~95% accuracy for MGC galaxies at B=18 and fainter.
· Analysis of a strip of 10 GSC2 HTM regions from |b|=90 to |b|=0 indicates that ~90% of stars have unanimous classifications down to |b|=30. Although the percentage falls as we approach the plane, the population rises even faster, so that the absolute number of unanimous stars is even higher in the plane than out of it. We found from the SDSS comparison (presented at the AAS last month) that unanimous classifications are extremely reliable in the comparison magnitude range (15.5 < F < 18.5). Thus, this finding that most stars in the catalog appear to have unanimous classifications is significant in terms of the functional use of the GSC2 to provide reliably classified guide stars. See http://www-gsss.stsci.edu/gsc/gsc2/calibrations/comparisons/calibrations_comparisons.htm.
CALIBRATIONS: Photometry (GSPC-II and DSS-I and -II)
· (Garcia Yus, CTIO.) Completed reduction of photometry from the latest CTIO run (December). The data include 76 new and/or reobserved sequences: 72 southern and 4 POSS-II fields. Additionally observed five fields with longer exposure times. Now the data need to be ingested into the pipeline catalog.
