CASB Report
February, 2001
·
Completed compressing the Equatorial Red (PPARC-ER)
plates scans, the final DSS-II red images that needed to be compressed. We now have all sky-coverage in both the red
and blue bandpasses.
· Supported two tours of CASB.
·
McLean and Greene continued supporting SDSS planning
activities.
· Reviewed one Guide Star Problem Report (GSPR) this period. This case was a search failure because the GS was a misclassified galaxy. Filed a Bad GS Alert.
· Released the Bright Object Tool in the VTT. This was in a special release of the VTT only for PI's who are doing STIS MAMA imaging. Until GSC-II is ready for release we will only be supporting STIS MAMA imaging.
· Now working on a version for the Instrument Scientists to perform bright object checking on Phase II proposals that come in for Cycle 10. The release date for that is currently March 22nd. Work for this release is going well.
· Morrison is participating in the NGST proposal writing.
·
Completed
scanning the current shipment of UKST-IR plates.
·
Resumed
scanning POSS-I O plates.
·
Sent a
shipment of 60 POSS-II N plates to ESO for copying.
·
Returned the
current shipment of UKST-IR plates to ROE.
·
Both scanning
machines are performing within specifications, but both are showing some signs
that they may require maintenance in the near term.
· Completed compressing the Equatorial Red (PPARC-ER) plates scans, the final DSS-II red images that needed to be compressed. We now have all sky-coverage in the red.
·
Continued
compressing scans of the POSSII-N and UKST-IR surveys.
· Waiting for new larger hard disks to be included in the raid arrays to help mitigate database storage needs, while allowing for the full migration of the the DSS to Chart.
· Remastered 10 CDROMs from the DSS for the National Astronomical Observatory of Japan.
·
No progress
reported in investigation of a GETIMAGE failure with the DSS-I, first reported
by the NAOJ Astronomical Data Analysis Center.
· In a very productive month, ran 228 plates (from both hemispheres) through the plate matching routine. Many of these required database loading as well, and a number represented problem plates encountered in attempting to complete the northern hemisphere.
· After completion of the load and match on the POSSII J and F plates, 19 remained unmatched. Identified and fixed problems with most of these. The fix required deleting and re-loading all the plates in the level 6 HTM region associated with the problem plate as well as deleting some individual corrupted objects. As a consequence a number of good plates as well as the problem plates needed to be deleted, reloaded, and rematched. Six plates remain unmatched in the north.
· Still investigating the exact failure mechanism, but it is probably related to the extreme number of detections in these fields. They represent the six most crowded regions in the north. An attempt to reprocess one of these fields using a higher detection threshold was unsuccessful. A call has also been placed to Objectivity regarding the possibility that we have encountered some sort of hard limit to storage in these failing regions.
· Several database regions in the south required restoring from the last backup when matching tasks revealed they were missing. Why the regions were missing is unclear, but dates point to the Objectivity administrative task of database file compression Ootidy.
· The files were restored and production has been running very smoothly in the south; fewer than 50 plates are required to complete loading.
· Plates with incorrect plate centers were corrected in both the production database and the test database. The CIQA procedure that discovered the problem now indicates the plate centers are correct on these plates.
· Continuing to run CIQA on plates in the test database.
· Began summary analyses of CIQA results for all plates run so far. Overlapping plate residuals in position and magnitude were studied for same-color pairs. Outlier values are quite high in some cases, but this is understandable since the test database contains our worst calibration cases. No systematic differences were observed between northern and southern hemisphere surveys.
· Developed an interactive utility to translate survey field to plate id, and vice versa, using the PSI database, to facilitate working with the database. A batch mode for the utility is also underway.
· Conducting a study determining the accuracy of the GSC-2.1 positions, using external catalogs (SPM,NMP, and 2MASS)
· Began experimenting with the use of the training set as a tool for visualization during the tree building process, and feedback during the tree application process.
