  1. Wide-Field Plate Database:Status and Pilot Projects Milcho K. Tsvetkov Sofia Sky Archive Data Center Bulgarian Academy of Sciences Strasbourg, November 29th, 2002 2002-2005 Action 283

  2. I.WFPDB Project History • Developed as a project of the IAU WG WFI, started in 1991 at the IAU GA in Buenos Aires (Argentina): WG WFI Chairman Richard West • Supported by: - the Bulgarian NSF 1993, F-311,340... - Alexander von Humboldt Foundation - Center for Informatics, Muenster University - German Research Council DFG • ESO, IAU and COST A283

  3. WFPDB Project Goals • Main Directions: • Catalog of WFPA: 345, 2x106 plates • Plate logs transformation • Search in WFPDB • Plate digitization • Relationship to other projects: Collaboration: CDS, ESO, IVO, GAVO, UDAPAC, SVO, HYPERLEDA, DENIS, etc.

  7. WFPDB: SEARCH

  8. STAR GAZER-Visualization!

  9. Team/Resources • State assumptions about resources, allocated for this project as a unit of the Bulgarian Academy of Sciences • locations: SOFIA, BAS - Campus 7km • people: 4As, 2PhD, 2St, 2Eng • equipment: SSADC, PDS, (UMAX), HPC • we support plate logs cataloging, database access, plate digitization, expert consultations, etc. WFPDB: Core project for the Bulgarian AstroGrid Development

  10. Competitive Analysis • Strengths • we have already cataloged and collected info for 1/3 of the existing WF plates; listed (practically) all existing ones; free internet access is provided via database search browser in Sofia and CDS, • Key role in the Bulgarian AstroGrid • Weaknesses • low speed of cataloging and visualization, bad website updating, but funding...

  11. Current PILOT Projects • Bamberg plate archive incorporation (“LMC” survey), fields preview • “Pleiades”: digitization of the 5° field around Alcyone for 100 yrs period • CWFPA version 5.0 • 2003 UMAX PL3000 flatbed scanners, involving in the plate digitization

  12. Bamberg plate archive incorporation: 2002-2003 • Bamberg plate archive: contains 32000 plates from Northern (10000) and Southern (22000) Surveys; Period 1928-1939(N) / 1963-1976 (S) • 13925 (43%) already cataloged and web available (2002), another 14000 (in early 2003): totally 28000 (88%) will be on line • 2003 UMAX PL3000 flatbed scanners, involving in the plate digitization

  13. Bamberg Photographic Patrol Sky Surveys • LMC plates from SBPPSS were selected and catalogued from all used telescopes and previews with CCD camera were made, including Mt. John and San Miguel Observatories plates • About 300 survey plates taken with Bamberg astrographs in Boyden, Lake Tekapo and San Miguel will be available via WFPDB in 2003. Previews of all plates will be added. Scanning of the plates will be done with UmaxPL3000Pro

  14. Pleiades Photographic Plate Database • WFPDB Search in VizieR (VI/90) about 3000 plates in the field of 5° • Plates are distributed in different observatories: from 1888-1990: Sonneberg, Harvard, Konkoly, Asiago, Byurakan, Rozhen, Bamberg, Tautenburg, UKSTU, etc.

  15. Pleiades Photographic Plate Database • Plate scanning is going in Konkoly, Sofia, Edinburgh, Cambridge (Bamberg and Sonneberg in progress). Already 400 plates are scanned from Konkoly, Rozhen, Potsdam, Bordeaux, Byurakan, UKSTU, Moscow... • The old scans from RGO (for about 300 plates in the database of Floor van Leeuwen) will be added.

  16. Pilot Projects cont. • USING COMMERSIAL FLATBED SCANNERS • Commercial flatbed scanners are already involved in the plate digitization: • Epson E1640XL, Asiago, DLR, (2003 Byurakan) (16 μ/pix) • MMO (USA) AGFA T5000 (10 μ/pix) . • UMAX PL3000Pro in Konkoly (2003 - Bambreg, Sofia, Harvard(?) (8 μ/pix) • Using HPC (MOSIX based) for data compression for the WFPDB purposes

  17. Future Projects • Orion Nebula M42/43: cataloging and plate digitization at the 5° field around “Trapezium” • Digitization of the plates in the field of M31: Already started in Asiago: they just completed M31 Asiago Schmidt telescope survey, 200 plates, from Asiago + 80 from Castle Gandolfo are scanned (C. Barbieri & F. Rampazzi).
