CASB Report for
September, 2000
·
Resumed
COMPASS load; 374 new plates loaded.
·
García is
visiting ESO headquarters and giving a talk about GSC2 photometry.
·
Garcia will
spend a week working with the OATo staff on GSPC2 PSF photometric analysis and
CIQA.
· Continued review of the CASB WWW pages.
· Obtained domain name for hosting IAU working group on sky surveys (skysurveys.org)
· Completed corrections to the GSC 1.2 paper suggested by the referee. Plan to send the final version of the GSC 1.2 paper to the AJ at the end of the month.
·
Continued
planning for the 6th annual GSC-II meeting, scheduled for Oct 19-20
2000.
· Installed Apache web server on NT for testing/evaluation.
·
Supported
meetings and budget estimates for SDSS-PA.
·
Submitted
proposals to NASA AISRP.
·
McLean
attended Project Management workshop.
· Reviewed six Guide Star Problem Reports (GSPRs) this period. Of these problems, five were fine lock failures due to close binaries. The search radius was exceeded for the sixth, which appears to be a misclassified faint galaxy. A Bad GS Alert was filed for each GS.
· Reviewed recent GS acquisition failures for observations of Canopus (Alpha Car). Determined that the magnitudes of guide stars from the Black Birch astrograph plate are progressively fainter at faint magnitudes compared to stars in common with GSC-II entries. Also, brighter GSs have been acquired successfully in other Canopus observations. SPSS plans to use only the latter GSs in future observations.
· Continuing work and consultations with Jesse Doggett on the Bright Object tool for the Visual Target Tuner (VTT).
· Morrison presented the status of finding suitable targets and associated guide stars, using the Tycho II Catalog, for the Nexus mission at GSFC.
· Continued project to refine the Nexus target/guide stars pairs using the GSC II database.
· Participated in writing the NGST Operations Concept and in supplying information on a suitable guide star catalog for NGST (a combination of 2MASS and GSC II).
·
Completed
scanning the latest shipment of UKST-IR plates.
·
Rescanned
several POSSI-E plates needed to complete GSC-II processing of the survey.
·
Resumed
scanning POSSII-N plates.
·
Returned
UKST-IR shipment to ROE; received a small additional shipment of POSSII-N
plates.
·
Sent five
requested plate scans to Cal Tech. Four
were remakes of unreadable data tapes due to the age of the tapes.
·
GAMMA1
continued to perform nominally during the previous month.
·
GAMMA2 is
temporarily out of service. A failure
of critical components resulted in an excess current detected in the servo
box. A circuit breaker tripped due to
the excess current, shutting down the scanning program. Replaced the failed parts and made
mechanical adjustments.
·
Completed a
subsequent scan, but post scan diagnostics showed unacceptable shearing. The shearing is unrelated to the original
failure and is believed to be due to problems in component assembly during the
mechanical work.
·
Continued
compressing scans of the POSSII-N and UKST-IR surveys.
· Resolved issues with two of the three remaining scan MODs with known problems.
· Continued writing MODs of UKST-IR scans.
·
Began setting
up the migration of the DSS1, DQVS, and XDSS compressed files from cd-rom to
hard disks on CHART.
·
No progress
reported in investigation of a GETIMAGE failure with the DSS-I, first reported
by the NAOJ Astronomical Data Analysis Center.
·
Completed
recalibration of 397 scans originally processed at ESO.
· Extended the production COMPASS plate load daemon to incorporate Object Matching. We are loading and matching approximately 20 plates per day.
· A COMPASS backup plan was developed for sectioning North and South in conjunction with production database operations. A DLT tape stacker has been installed for DB backup automation. This will reduce the 1+ week backup time to a few days with minimal tape handling.
· Developed and tested the version of Plate and Reference Catalog Matching for the COMPASS Object Index utilizing the HTM. The initial performance analysis shows that this method feasibly provides a very fast cross-correlation between large data sets. Tolerance settings are being explored to achieve acceptable match quality.
· Successfully installed the JAVA ShowSky utility on a Linux system and also delivered it to SDSS Science Archive collaborators. This utility is also currently being used for QA of classification algorithms. An interface to remote SDSS test data has also been developed and will be scheduled for implementation and testing.
· Repair to corrupted database regions is underway. There are 3 HTM level 6 DB region files with corrupted Object Index containers. These regions have been restored from previous versions. The plates loaded in these regions will require re-matching.
· Did more work on fine-tuning the astrometric filtering algorithm.
· Created a versatile version of the classifier without hard-coded classifications, which makes use of the FITS format decision tree file reported the last month. Preliminary results with adding galaxies and blends as classifications appear promising, but clearly more work is needed.
· An experimental training set and associated decision tree has been created, using catalog objects for stars and galaxies, and parent objects for blends. It extends only to 17.5 magnitude (F band, OOP magnitude) due to limitations in the catalogs used. Preliminary results of un-deblended objects in the corresponding magnitude range show a majority of correct results for objects that changed classifications. Analysis of these results continues, as do efforts to further extend the training set.
· Reviewed the convert_ranks program and began a redesign of the rank tables into a FITS format that will be more amenable to experimenting with different sets of features.
CALIBRATIONS: Photometry (GSPC-II and DSS-I and -II)
·
Built a new
GSPC-II export catalogue, using the criteria presented in the paper and adding
observation times and magnitude errors for the case of multiple data.
·
Submitted
proposals for additional observing time at JKT-La Palma and CTIO.
·
Continued working on proper motion science projects; trying to find an
accurate solution for the black-hole N23203203594 proper motion.
·
Submitted proposal for follow-up observations of high-proper motion
stars.
