This service implements the Identifiers 2.0
suggestion for how to resolve an IVOA publisher dataset identifier;
that is, it tries to resolve the registry part to Datalink,
SSAP, or Obscore capabilities and tries those to find access URLs.
If that fails, it repeats this procedure for services that the
base resource declares as served-by.
The code used here is available at

Gravitational arc candidates in the CFHTLS-Archive-Research Survey

Description:
Candidate gravitational arcs in the 37 deg^2 of
CFHTLS-Archive-Research Survey (CARS). The data include their
post-stamp images, astrometry, photometry (u*,g',r',i'), geometric
properties (length, length-to-width ratio, profile curvature, area),
and photometric redshifts. The arc candidates were selected booth with
an automatic arcfinder, based on a tailored image segmentation and a
color selection, and by visually inspecting the survey.
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.
High-Resolution Very Large Array Imaging of Sloan Digital Sky Survey
Stripe 82 at 1.4 GHz

The GAVO DC team
Description:
This is a high-resolution radio survey of the Sloan Digital Sky Survey
(SDSS) Southern Equatorial Stripe, a.k.a. Stripe 82. This 1.4 GHz survey
was conducted with the Very Large Array (VLA) primarily in the
A-configuration, with supplemental B-configuration data to increase
sensitivity to extended structure. The survey has an angular resolution
of 1.''8 and achieves a median rms noise of 52 μJy per beam over 92 deg^2.
The catalog contains 17,969 isolated radio components, for an overall
source density of ∼195 sources/deg^2. See also J.A. Hodge et al,
:bibcode:`2011AJ....142....3H` .
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 services provides 1D spectra from DR5 of LAMOST (Large Sky Area
Multi-Object Fiber Spectroscopic Telescope) through SSAP;
data is served both in VO-standard SDM and, via datalink, the original
SDSS-inspired FITS described in
http://dr5.lamost.org/doc/data-production-description .
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).
