I.I.WFPDB WFPDB Project HistoryProject 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... - AvH Stiftung (4 donations!) - RZ Muenster University (SHPC)
ESO and the IAU
WFPDB Project GoalsWFPDB Project Goals
Main Directions:– Catalog of WFPA: 2x106 plates – Plate logs transformation – Search in WFPDB – Plate digitization directions
Relationship to other projects: Collaboration: CDS, ESO, IVO, UDAPAC, SVO, etc.

State assumptions about resources, allocated for this project as a unit of the Bulgarian Academy of Sciences – people: 4As, 2PhD, 2St, 2Eng– equipment: SSADC, HPC, PDS, (UMAX)– locations: SOFIA, + virtual Go!ICQ– we support plate logs cataloging, database
access, plate digitization, expert consultations, etc.
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
Weaknesses– low speed of progress, bad website
updating, funding...
Competitive Analysis (cont.)Competitive Analysis (cont.)
More weaknesses: - deadtime of the changes between
generations: about 2 years each 4-5 years
Related activities: SSADC, BG AstroGrid, EC-COST national representation, European Week of ST since 1996, websiting Humboldt Union in Bulgaria, etc.

Northern Patrol Sky Survey - 1928/1939 as a program of P.Guthnick and directed by E. Zinner,
Telescopes: astrographs (1939/1956)Observers: Ruegemer and BoehmeTotal number of plates about 10000

Advantages: -All plates are available on site; period of monitoring 1928-1939; one type emulsion used (Matter); homogeneous; good plate conditions
Disadvantages: - no logs: but 6400 plates of Ernostar 1928-1939) are cataloged from the stacks during the visits in 2001 and 2002; other 4000 plates need cataloging; low limit 12-13pg; coma in plate field;
Cameras view now: Emulsion used: Matter

Field of priority for WFPDB team last years ! History: Started as alternative and continuation of
the BNSS in 1963. Initiators: K. Strohmeier, R.
Knigge, etc. Program for southern variable star search, supported by DFG.
Equipment: 10 cameras (10/61 cm) were received from Baush&Lomb Ltd and completed as a multiple astrograph in the Bamberg workshop.
Later on 4 cameras were sent to New Zealand (Mt. John University observatory (Leo Tekapo) and another 4 cameras were used in San Miguel Station, Argentina

Contains at the present statistics: - 22000 plates: 12567+1358
are already incorporated in the WFPDB
Advantages: Unique survey for 1963-1976; perfect log books; very accurate recording the time of observations (1minute); plates available on site in good conditions; plate preview (jpg 1MB/3.5 MB tiff) will be provided; further plate digitization on site will be organized, web access is now made (WFPDB) for 13 925 plates

Unexpected delays and disadvantages: more than 6000 plates from New Zealand/Argentina survey out of the logs, need cataloging, used in 1963-64 not sensitive emulsion (Perutz), some mistakes in the logs and misplaced plates out of order; old emulsion used (in Argentina), comparatively not homogeneous - different limiting magnitude: from 10-11pg (1963) to 14-15pg in (1970)

WFPDB team actions in 2002: - Start CCD preview imaging for each zone(RA/D) up to now was completed preview practically for all survey(-90,-77,-64,-51- 38,-25,-12 zones) 6 CD contain about 3000 preview images in JPG format (April and September-November)
Computer readable form for plate logs completed, proved and converted in the database format for 13000 plates!
First test access to the Database in Sofia realized successfully!
Visualization of the plate field was provided via SSADC-StarGazer routine!

LMC survey from SBPPSS was selected and catalogued from all used telescopes and previews with CCD camera were made, including Mnt. John and San Miguel plates
BBW76 Fuor like object (12-13 pg) was studied on the Bamberg plates as an example for plate archive importance.
Discussions and arrangements about the DFG/ AvH Stuftung donations and joint project development was evaluated.
