Smithsonian Astrophysical Observatory Telescope Data Center
Description:
This catalog contains derived information and access to spectra for a
catalog of objects in the field of M31, drawn from the study of star
clusters, HII regions, PNe and individual stars in M31 done with
Hectospec on the MMT by Nelson Caldwell and a host of others.
Stripe 82 Photometric Redshifts from SDSS Coadditions
Short Name:

The GAVO DC team
Description:
This survey gives photometric redshifts of objects within 275 deg²
(−50◦ < α < 60◦ and −1.◦25 < δ < +1.◦25) centered on the Celestial
Equator. Each piece of sky has ∼20 runs of repeated scanning by the
SDSS camera contributing and thus reaches ∼2 mag fainter than the SDSS
single pass data, i.e., to r ∼ 23.5 for galaxies.
The SuperCOSMOS data primarily originate from scans of the UK Schmidt
and Palomar POSS II blue, red and near-IR sky surveys. The ESO Schmidt
R (dec < -17.5) and Palomar POSS-I E (dec > -17.5) surveys have also
been scanned and provide an early (1st) epoch red measurement.
Mirrored here is the source table containing four-plate multi-colour,
multi-epoch data which are merged into a single source catalogue for
general science exploitation. Within the GAVO DC, some column names
have been adapted to local customs (primarily positions, proper
motions).

Description:
4XMM-DR13, released by the XMM-Newton Survey Science Centre (XMM-SSC)
in collaboration with the SOC.
This version includes an extra year of data with respect to 4XMM-DR12.
4XMM-DR13 includes 983948 X-ray detections which relate to 656997 unique X-ray sources
from 13243 observations that were public by the 31st December 2022. 4XMM-DR13 covers
a total sky area, with at least 1 ks exposure, of 1328 square degrees if overlaps are
taken into account, where some regions of the sky have been pointed as many as 90 times.
Around 9% of all the detections are classified as extended, and spectra and time series
have been extracted for 36% of the detections.
The median positional uncertainty of the catalogue detections is 1.57 arcseconds (with a standard deviation of
1.43). Median fluxes in the catalogue are ~5.2E-15 and ~1.2E-14 erg/cm2/s in the soft (0.2-2 keV) and hard
(2-12 keV) X-ray band, respectively.
The TAP server for Konkoly's TAP end point. The Table Access
Protocol (TAP) lets you execute queries against our database tables,
inspect various metadata, and upload your own data. It is thus the
VO's premier way to access public data holdings.
Tables exposed through this endpoint include: columns, groups, key_columns, keys, schemas, tables from the tap_schema schema, epn_core from the sbnaf schema.
