The Armagh-Dunsink-Harvard Becker-Schmidt Telescope was deployed at
Boyden Station, Maselspoort South Africa between 1965 and 1970. During
that time, astronomers from Bamberg, Heidelberg, Hamburg and Münster
took astronomical images there, with a focus on old star clusters, the
Magellanic clouds, and the southern milky way. This service provides
scans of the plates obtained.
This table holds metadata for the “Patrol” and “Meteor” plates from
DASCH, i.e., very wide-field observations presumably not useful in
global discovery. These data products are therefore not re-published
through obscore. For the “narrow” plates, see the narrow_plates table.
This table holds metadata for the parts of DASCH counting as targeted
observations (plate scale below 400 arcsec/mm. “Patrol” and “Meteor”
plates in DASCH nomenclature are found in the wide_plates table.
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.
GAVO's historical photographic plate archive (GHHPA) is a
collection of various digitized historical photographic
plates. It currently exposes:
* the scans of plates of selected Kapteyn special fields obtained
at Potsdam
* the Palomar-Leiden Trojan surveys, 1960-1977,
* a collection of plates obtained at Boyden Station, South Africa,
kept at various German observatories.
Other plate collections kept by GAVO include the Heidelberg
Digitized Astronomical Plates HDAP,
ivo://org.gavo.dc/lswscans/res/positions/siap, and the APPLAUSE
database from Potsdam.
This tutorial introduces a few techniques for working with image
services in the Virtual Observatory (VO) in general, using services
containing plate scans as examples. It will discuss both exploratory,
interactive use, and scripting using pyVO.
From 1986 through 1991, the Astronomical Institute of Münster
University performed a search for flare stars in several southern
associations and open stellar clusters using the GPO telescope (d=40
cm, WFPDB identifier ESO040); the fields suveyed include Coalsack,
M42, B228 Lup, the Chameleon T1 association, omicron Vel cluster, R
CrA association, the Pipe nebula (B59 Oph), and the Sco-Oph
association. This was done primarily through multiple exposures. The
files published here are plate scans done in 2017.
The obscore collection name for these files is Muenster Flare Survey.
In the context of Kapteyn's plan to obtain a photometric standard, in
Potsdam more than 400 photographic plates of several Selected Areas,
Special Areas, and Kapteyn-Pritchard areas were obtained between 1910 and
1933, both as direct images and with an object prism. This service
provides FITS images of the science area of the plates as well as images of
the entire plates, including previous markings.
