CASB Report January,
2002
·
Completed
compressing the selected scans of all POSSII-N plates received from Palomar.
·
Received a
special shipment of the last two available POSSII-N plates from Palomar.
·
Several CASB members attended the 199th
AAS Meeting in
·
R. White and V.
Laidler displayed a poster at the January AAS Meeting: "GSC2.2 vs SDSS Astrometry, Photometry, and Classification."
·
D. Carollo, S. T. Hodgkin, A. Spagna, R. L.
Smart, M. G. Lattanzi, and B. McLean also displayed a poster at the
meeting: “Discovery of a Dwarf Carbon Star
toward the NGP.” They have submitted a
paper on this research to A&A.
·
A. Rosenberg and A. Storrs (
·
Laidler prepared
and presented a talk at the AURA Software Workshop: "OCtoo:
A Classification Software Package".
·
Greene prepared
and presented a talk at the AURA Software Workshop: "Database Technologies
for Astronomical Archives".
·
Prepared
contributions for the GSC2 multimedia CD project.
·
Updated the GSC2
Calibrations/Comparisons page to include the new SDSS comparison results.
· Daniela Carollo of OATo has visited STScI for 20 days to support selection of additional high proper motion objects from the original plate scans and GSC2 processing files to support the search for halo white dwarf candidates.
· Antonio Volpicelli started comparison of Objectivity and MS SQLserver for GALEX/GSC-II
·
McLean and Greene continued supporting SDSS
planning activities.
· Reviewed 9 new Guide Star Problem Reports (GSPRs) this period. Seven of these were fine lock failures. One of the other GSPRs documented loss of lock during re-acquisitions due to the faintness of the star, possibly a nearby star too faint to be in GSC1. The remaining GS also was too faint and failed to maintain coarse track. Filed a Bad GS Alert for each of the GSs.
·
Continuing the
· Continued to obtain statistics of webserver visits, specifically, accessing of GSC2.
· Occasionally answering questions from the APT team about the Bright Object Tool.
· Collecting responses about the draft HUGS2 report
· Scanning UKST-IR plates from the current ROE shipment.
· Returned 44 of the plates from this shipment to ROE, including several high-priority plates that they had requested.
· Received a special shipment of the last two available POSSII-N plates from Palomar. Of the two fields covered by these plates, one would have been difficult and the other impossible to observe with the UK Schmidt.
· After the power outage of 29 December, some of the devices on pixel1 did not come back on line. These included two directories containing two completed scans not yet archived. Thomas Walker was able to restart the disks, saving the scans. Loomis then was able to restart the scanning program and production scanning resumed 11 January.
· GAMMA2 is still down; performed no production scans on GAMMA2 throughout he period.
· The low number of production scans this month is due mostly to the above problems.
·
Completed
compressing the selected scans of all POSS-II-N plates received from Palomar (except for the two plates just received).
· Completed migration of all red and blue XDSS CDROMs to the RaidTec NFS raidarray.
· A total of 766 CDROMs with 475GB of compressed files has been transferred.
· Started migration of the IR XDSS CDROMs.
· Loaded the third set of CDROMs (~300) in the carriages in preparation to continue copying.
· Worked on one archive help desk request for help/information.
· Continued low-level rationalization of MOD archive.
·
Continued
processing POSS Quick V plates.
·
Restarted
processing of the POSS-II-N survey.

(OATo)
Halo White Dwarf Project. Daniela Carollo is working on the
selection and processing of ~ 15 regions toward the NGP in order to cover an
area of 400 deg2.
The high proper motion objects selected from these fields will increase the
sample of halo WD candidates. The spectroscopy follow-up of this sample will be
in April at
· OATo and CASB staff also report the discovery of a new dwarf carbon star (GSC2U J131147.2+292348) that has been serendipitously identified during the proper motion survey for cool white dwarfs. Its large proper motion (0.48 as/yr) and its faint apparent magnitude (V~ 18.7) suggest a nearby object of low luminosity. In addition, a low resolution spectrum taken with the William Herschel Telescope clearly shows the strong C2 bands and confirm the dwarf nature of the carbon star. They derive the absolute magnitude limit of M_V >13.5 from its kinematic properties; it appears significantly fainter than the other dC stars for which accurate luminosities have been determined using trigonometric parallaxes (Harris et al. 1998). Finally, the spectrum shows an unexpectedly strong emission below 4700 A This could be an indication of the presence of a bluer secondary component.
