Title:: BGDS Mean Photometry Cone Search
Short Name:: BGDS mean phot
Date:: 27 Dec 2024 08:31:01
Publisher:: The GAVO DC team
Description:: Extracted sources from the Bochum Galactic Disk Survey. We provide mean photometry in U, B, V, z, r, and i bands. Note that sources in different bands are not matched. Also, sources sitting in the regions imaged in multiple fields have not been matched even within one band. In i and r, BGDS light curves are available. See related services for details.

Title:: Bochum Galactic Disk Survey (BGDS) light curves
Short Name:: BGDS TS SSAP
Date:: 27 Dec 2024 08:31:01
Publisher:: The GAVO DC team
Description:: 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.

Title:: Coordinated microlensing survey observations with Kepler K2/C9 using VST
Short Name:: k2c9vst ssap
Date:: 27 Dec 2024 08:31:04
Publisher:: The GAVO DC team
Description:: The Kepler satellite has observed the Galactic center in a campaign lasting from April until the end of June 2016 (K2/C9). The main objective of the 99 hours for the microlensing program 097.C-0261(A) using the ESO VLT Survey Telescope (VST) was to monitor the superstamp (i.e., the actually downloaded region of K2/C9) in service mode for improving the event coverage and securing some color-information. Due to weather conditions, the majority of images were taken in the red band. These are part of the present release. The exact pointing strategy was adjusted to cover the superstamp with 6 pointings and to contain as many microlensing events from earlier seasons as possible. In addition, a two-point dither was requested to reduce the impact of bad pixels and detector gaps. Consequently, some events were getting more coverage and have been observed with different CCDs. The large footprint of roughly 1 square degree and the complementary weather conditions at Cerro Paranal have lead to the coverage of 147 events (this resource's events table), but ~60 of those were already at baseline.

Title:: Gaia DR2 epoch fluxes
Short Name:: gaia.dr2epochflu
Date:: 27 Dec 2024 08:31:02
Publisher:: The GAVO DC team
Description:: A table of the light curves released with Gaia DR2 (about half a million in total). In each Gaia band (G, BP, RP), we give epochs, fluxes and their errors in arrays. We do not include the quality flags (DR2: “may be safely ignored for many general purpose applications”). You can access them through the associated datalink service if you select source_id. You will usually join this table with gaia.dr2light. We have also removed all entries with NaN observation times; hence, the array lengths in the different bands can be significantly different, and the indices in transit_ids do not always correspond to the indices in the time series. Furthermore, we only give fluxes and their errors here rather than magnitudes. Fluxes can be turned into magnitude using:: mag = -2.5 log10(flux)+zero point, where the zero points assumed for Gaia DR2 are 25.6884±0.0018 in G, 25.3514±0.0014 in BP, and 24.7619±0.0019 in RP (VEGAMAG).

Title:: Gaia DR2-light Cone Search
Short Name:: GDR2light SCS
Date:: 27 Dec 2024 08:31:02
Publisher:: The GAVO DC team
Description:: This schema contains data re-published from the official Gaia mirrors (such as ivo://uni-heidelberg.de/gaia/tap) either to support combining its data with local tables (the various Xlite tables) or to make the data more accessible to VO clients (e.g., epoch fluxes). Other Gaia-related data is found in, among others, the gdr2dist, gdr3mock, gdr3spec, gedr3auto, gedr3dist, gedr3mock, and gedr3spur schemas.

Title:: Gaia DR2 light curves SSA
Short Name:: GDR2 TS SSAP
Date:: 27 Dec 2024 08:31:02
Publisher:: The GAVO DC team
Description:: This service exposes about 0.5 million light curves of stars classified as variable by the Gaia analysis system through the VO SSAP protocol. The lightcurves are published per-band and are also available through obscore.

Title:: Gaia DR2 source catalogue "light"
Short Name:: gaia.dr2light
Date:: 27 Dec 2024 08:31:02
Publisher:: The GAVO DC team
Description:: This is a “light” version of the full Gaia DR2 gaia_source table, containing the original astrometric and photmetric columns with just enough additional information to let careful researchers notice when data is becomes uncertain and the full error model should be consulted. The full DR2 is available from numerous places in the VO (in particular from the TAP services ivo://uni-heidelberg.de/gaia/tap and ivo://esavo/gaia/tap). This table also includes a column containing the Renormalized Unit Weight Error RUWE (GAIA-C3-TN-LU-LL-124-01), a robust measure for the consistency of the solution. On this TAP service, there is the table gdr2dist.main containing distances computed by Bailer-Jones et al (:bibcode:`2018AJ....156...58B`). If in doubt, use these instead of the parallaxes provided here.
