WFPDB: The Bamberg Plate Archive Incorporation - Status November 2002 Milcho K. Tsvetkov Sofia Sky Archive DataCenter Bulgarian Academy of Sciences Bamberg, …. still not 11h :) Dr. Karl Remeis

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, AvH Stiftung (4 donations!) - RZ Muenster University (SHPC) ESO and the IAU

WFPDB Project Goals Main Directions: –Catalog of WFPA: 2x10 6 plates –Plate logs transformation –Search in WFPDB –Plate digitization directions Relationship to other projects: Collaboration: CDS, ESO, IVO, UDAPAC, SVO, etc.

More Descriptions: Ask me at the address: Website: FOR MORE INFO...

Team/Resources Team/Resources 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 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.) 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.

Schedule: Bamberg plate archive incorporation (“LMC” survey), previews 2002 “Pleiades”: pilot project started 2003 CWFPA version UMAX PL3000 flatbed scanners, involving in the plate digitization Complement of the WFPDB up to plates - 50% from all!! MORE!!!

II. BAMBERG: - Current Status History: 1st visit in December Mr. R. Knigge’s introduction Study visits in the : started plate logs cataloging in Sofia 2001: Joint project preparation via AvH stiftung and DFG 2002/03 AvH stay and start of the DFG project ( )

Dr. Remeis Observatory-Bamberg Photographic Patrol Sky Surveys Northern Patrol Sky Survey /1939 (Ernostar A,B) - Tessar’s, Dogmar, Xenon and Small Schmidt: up to 1965 Southern Patrol Sky Survey - Boyden: (BAM010A-J) - Mnt. John: (BAM010G-J) - San Miguel: (BAM010K-N)

Northern Bamberg Photographic Patrol Sky Surveys Northern Patrol Sky Survey /1939 as a program of P.Guthnick and directed by E. Zinner, Telescopes: astrographs (1939/1956) Observers: Ruegemer and Boehme Total number of plates about 10000

Northern Bamberg Photographic Patrol Sky Surveys Advantages: -All plates are available on site; period of monitoring ; one type emulsion used (Matter); homogeneous; good plate conditions Disadvantages: - no logs: but 6400 plates of Ernostar ) 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

Southern Bamberg Photographic Patrol Sky Surveys Field of priority for WFPDB team last years ! History: Started as alternative and continuation of the BNSS in Initiators: K. Strohmeier, R. Knigge, etc. P rogram 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

Southern Bamberg Photographic Patrol Sky Surveys Contains at the present statistics: plates: are already incorporated in the WFPDB Advantages: Unique survey for ; 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 plates

Southern Bamberg Photographic Patrol Sky Surveys Unexpected delays and disadvantages: more than 6000 plates from New Zealand/Argentina survey out of the logs, need cataloging, used in 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 pg in (1970)

Southern Bamberg Photographic Patrol Sky Surveys 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, ,-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 plates! First test access to the Database in Sofia realized successfully! Visualization of the plate field was provided via SSADC-StarGazer routine!

Southern Bamberg PPSS: WFPDB team actions in 2002 Cont. 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.

WFPDB: FIRSTSEARCH for Bamberg Plates: NOW h AM !

STAR GAZER-Visualization!

2003 actions 2003 actions More previews needed for because of the low limit start with the preview of the ERNOSTAR HAR025 (Metcalf 10”) plate preview will be made using the new scanner because of the plate size. UMAX PL3000 Pro flatbed scanner installation and start of test scans.

UMAX PL3000 Pro 2001 search for suitable scanner thanks the DFG such scanner will be provided for Bamberg in 2003 (April) UMAX PL3000 Pro flatbed scanner description

PLATE DIGITIZATION in Bamberg Each plate contains information - 250x2=500 MB (with 8 microns resolution) Recording the scanned plates on DVD (8 plates on one DVD) Start digitization of the LMC and Pleiades fields. Preparation of a dataset of LMC fields and report at the IAU GA in Sidney
