Description:
This is a catalog of 5437 morphologically classified sources in the
direction of the Perseus galaxy cluster core, among them 496
early-type low-mass galaxy candidates. The catalog is primarily based
on V-band imaging data acquired with the William Herschel Telescope.
Additionally, we used archival Subaru multiband imaging data in order
to measure aperture colors and to perform a morphological
classification. The catalog reaches its 50 per cent completeness limit
at an absolute V-band luminosity of -12 mag and a V-band surface
brightness of 26 mag arcsec^-2 .
In addition to the published table, this service also contains cutout
images of the objects investigated.
The archive of AGN spectral observations is obtained on AZT-8
telescope at the Fesenkov Astrophysical Institute (FAI), Almaty,
Kazakhstan. It represents the result of observations for abot 25 years
- from 1970 to 1995. All observations were carried out at AZT-8 (D =
700 mm, F[main] = 2800 mm, F[Cassegrain] = 11000 mm) with a high-power
spectrograph. In 1967-68, on the basis of the image intensifier
(https://doi.org/10.1080/1055679031000084795a) developed and assembled
the spectrograph of the original design in the workshops of the FAI.
To use the spectra, please, download raw .fit file of required object,
date and exposure. The open 'Calibration frames' in Related links and
then use them to calibrate object spectra frames. For more information

Description:
This DSA hosts data release 1 of the ATLAS Survey housed at the Wide Field Astronomy Unit at the Univeristy of Edinburgh. The initial aim of ATLAS is to survey 4500 deg2 of the Southern Sky at high galactic latitudes to comparable depths to the SDSS in the North. The VST ATLAS will be the first step towards a panoramic digital survey of the Southern Sky in the optical bands. The ATLAS will complement the proposed VISTA Hemisphere Survey in the South.
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 service exposes the light curves of stars produced by the Bochum
Galactic Disk Survey; several million light curves are provided in the
SDSS i and r bands. The lightcurves are published per-band and are
also available through obscore.
The CADC provides a collection of reference surveys available using the HiPS protocol. All collections are clones of the main HIPS server at CDS (http://aladin.u-strasbg.fr/hips/). Additional services will be added as they become available.
Split spectra from the CALIFA DR3 cubes. This service serves one
spectrum each per pixel in each cube where there is at least one valid
spaxel. Where both V500 and COMB data is available, COMB spectra are
served. WARNING: The individual spectra are not independent. Also,
error estimates over wide spectral ranges based on the error estimates
served here are unreliable.
YouCat is a query service for catalogues hosted by CANFAR. This service
provides Table Access Protocol (TAP) API access to catalogues created by
project teams.
YouCat also implements a prototype VOSI-tables extension that allows users
to create, update table metadata add table content (rows), create indices,
and delete tables in the database. Users can also control access to their
own tables (public to allow anonymous querying, protected so only members
of specified groups can query, and private where only the owner can query).
Users who want to create tables must request an allocation (schema) by email
to support@canfar.net.
Currently available catalogues include: VLASS, CFHTLS, KiDS, PAndAS, RCSLens.
The Chandra X-ray Observatory Data Archive provides a reference survey
via the HiPS protocol.

The Chandra X-ray Observatory is the U.S. follow-on to the Einstein
Observatory. Chandra was formerly known as AXAF, the Advanced X-ray
Astrophysics Facility, but renamed by NASA in December, 1998.
Originally three instruments and a high-resolution mirror carried in
one spacecraft, the project was reworked in 1992 and 1993. The Chandra
spacecraft carries a high resolution mirror, two imaging detectors,
and two sets of transmission gratings. Important Chandra features are:
an order of magnitude improvement in spatial resolution, good
sensitivity from 0.1 to 10 keV, and the capability for high spectral
resolution observations over most of this range.
Execution service - implemented in the Common Execution Architecture - that generates context information on-demand. This service provides one or more science applications that are registered separately
Service that performs transformation between coordinate sets. Service is implemented in the Common Execution Architecture and is in fact part of the CXS.
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.

Description:
Catalog of astrometry and photometry of detected point sources in the Far red optical (0.82-micron I-band) and near-infrared (1.25-micron J- and 2.15-micron Ks bands). ~16,700 square degrees of the southern sky
WFAU, Institute for Astronomy, University of Edinburgh
Description:
The 6dF Galaxy Survey (6dFGS) aims to measure the redshifts of around 150 000 galaxies, and the peculiar velocities of a 15 000-member subsample, over almost the entire southern sky. The table called Spectra contains the redshifts and qualities of all the observations. When complete, it will be the largest redshift survey of the nearby Universe, reaching out to about z ~ 0.15, and more than an order of magnitude larger than any peculiar velocity survey to date. The targets are all galaxies brighter than K tot = 12.75 in the 2MASS Extended Source Catalog (XSC), supplemented by 2MASS and SuperCOSMOS galaxies that complete the sample to limits of (H, J , r F, bJ) = (13.05, 13.75, 15.6, 16.75).
