The Bochum Galactic Disk Survey is an ongoing project to monitor the
stellar content of the Galactic disk in a 6 degree wide stripe
centered on the Galactic plane. The data has been recorded since
mid-2010 in Sloan r and i simultaneously with the RoBoTT Telecsope at
the Universitaetssternwarte Bochum near Cerro Armazones in the Chilean
Atacama desert. It contains measurements of about 2x10^7 stars over
more than seven years. Additionally, intermittent measurements in
Johnson UVB and Sloan z have been recorded as well.
This is a deep optical mosaic of the Fornax cluster’s core, covering
1.6 square degrees. The data were acquired with ESO/MPG 2.2m/WFI,
using a transparent filter that nearly equals the no-filter throughput
and thus provides a high signal-to-noise ratio. Based on an
approximate conversion to V-band magnitudes, the unbinned and binned
mosaics (0.24 and 0.71 arcsec/pixel) reach a median depth of 26.6 and
27.8 mag/sq.arcsec, respectively.
The GAVO Data Center's sitewide SIAP version 2 service
publishes all the images published through the site. For more advanced
queries including uploads, all this data is also available through
ObsTAP.
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.
A collection of images of lensed quasars from various sources.
Included are images from Maidanak Observatory
(ivo://org.gavo.dc/maidanak/res/rawframes/siap), Apache Point
Observatory, from the MiNDSTEp project
(ivo://org.gavo.dc/danish/red/q), and from the Liverpool Robotic
Telescope (ivo://org.gavo.dc/liverpool/res/rawframes/q).

Description:
These FITS images were generated with the IDL package MIRphot
[Asmus2014]_ by extraction (and combination) of the sub-images from the
chopped/nodded total images from COMICS, Michelle, T-ReCS and VISIR (see
[Asmus2014]_ for details).
The FITS images contain the central ~4 arcsec of each source centered on
the (putative) nuclear position with North being up and East to the
left. The WCS registration has been performed after extraction by using
coordinates of the nucleus from other wavelengths (mostly 2MASS and
NED). The uncertainty of these reference position is usually less than 1
arcsec. In addition, the imprecision of the assignment itself is ~1px ~
0.1".
The FITS images are flux calibrated (unit is mJy) using the Gaussian 2D
fits to the corresponding STD observation (where available, otherwise
using the median conversion factor for the used instrument/filter
settings). Therefore, correction factors have to be applied in case
other flux measurement methods are applied to the images. The flux
values given in the FITS headers should be regarded as approximate
values. In particular for the instruments, VISIR and COMICS, they are
not necessarily exactly equal to the values provided in the photometry
results table, because many flux measurements were performed during the
process of combining individual subimages (all in MIRphot), instead of
in the final combined image, provided here. The used total images are
available upon request. Note, however, that these are just the products
of the observatory-delivered pipelines with default parameters.
