News

2014-11-14 (MD): There's now a web page showing the Wolf-Palisa survey as part of HDAP.
2013-08-02 (MD): New plate catalogue, including many very early Wolf plates. 14277 plates in the database.
2011-08-22 (MD): Full plate access now supports returning scaled plates and supports querying by position.
2011-03-18 (MD): New plate catalogue, plus there are now uncalibrated plates in the database. Search for those using the plate search. There are now 8001 plates in DB.
2010-12-19 (MD): New plate catalogue, 7479 plates in DB
2010-05-19 (MD): New plate catalogue, 6677 plates in DB
2010-02-19 (MD): New plate catalogue, 6159 plates in DB. B3282b was deleted since it really was a different plate. The real B3282b is unusable.
2009-12-03 (MD): New plate catalogue, 6160 plates in DB.

Description

Scans of plates kept at Landessternwarte Heidelberg-Königstuhl. They were obtained at location, at the German-Spanish Astronomical Center (Calar Alto Observatory), Spain, and at La Silla, Chile. The plates cover a time span between 1880 and 1999. Specifically, HDAP is essentially complete for the plates taken with the Bruce telescope, the Walz reflector, and Wolf's Doppelastrograph at both the original location in Heidelberg and its later home on Königstuhl.
