WFPDB Project GoalsWFPDB 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.

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

Competitive AnalysisCompetitive 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...

Current PILOT ProjectsCurrent 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 Developing consortium of organizations

equipped with commercial flatbed scanners (f.e. like ESPON 1640XL) involving in the plate digitization (Italy, Germany, Armenia, Bulgaria, Hungary, Romania, Ukraine, etc.

ConclusionsConclusions

inventory! INVENTORY!! INVENTОRY!!! most important moment for the WFPDB progress is to increase the

speed of the plate logs converting in

the WFPDB format! the time of logs converting is

comparable with the plate scanning!

Bamberg plate archive Bamberg plate archive incorporation: 2002-2003incorporation: 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

EPSON Expression 1640XL flatbed scanner, involving in the plate digitization

Bamberg Bamberg Photographic Patrol Sky SurveysPhotographic 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 the flatbed scanner Epson 1640XL.

Pleiades Pleiades Photographic Plate DatabasePhotographic 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.

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.

•USING COMMERSIAL FLATBED SCANNERS!!!•Commercial flatbed scanners are already involved in the plate digitization:• Asiago, DLR, Byurakan, Sofia, Bamberg

Epson Expression 1640XL(16 μ/pix)• MMO (USA), AGFA T5000 (10 μ/pix) .• Sonneberg , HP 7400 (4 scanners) (20 μ/pix)• Konkoly, UMAX PL3000Pro (8 μ/pix)• Using HPC (MOSIX based) for data compression for the WFPDB purposes

Future ProjectsFuture Projects

• Orion Nebula M42/43: cataloging and plate digitization at the 5° field around “Trapezium”• NGC 2264• 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).
