Title:: Astrometric Microlensing Events Predicted from Gaia DR2
Short Name:: am lensing 2
Date:: 27 Dec 2024 08:31:01
Publisher:: The GAVO DC team
Description:: From the Gaia DR2 catalogue we predict astrometric microlensing events by foreground stars with high proper motion (µ_tot >150mas/yr) passing a background source in the next decades. Using Gaia DR2 photometry we determine an approximate mass of the lens, which we use to calculate the expected microlensing effects. This yields 3914 microlensing events by 2875 different lenses between 2010 and 2065 with expected shifts larger than 0.1 mas between the lensed and unlensed positions of the source. 513 of those are expected to happen between 2014.5 - 2026.5 and might be measured by Gaia. For 127 events we also expect a magnification between 1 mmag and 3 mag.

Title:: Astrometric Microlensing Events Predicted from Gaia eDR3
Short Name:: am lensing 2
Date:: 27 Dec 2024 08:31:05
Publisher:: The GAVO DC team
Description:: From the Gaia eDR3 catalogue we predict astrometric microlensing events by foreground stars with high proper motion (μ > 100 mas/yr) passing a background source in the next decades. Using Gaia DR3 photometry we determine an approximate mass of the lens, which we use to calculate the expected microlensing effects. This yields 4842 microlensing events by 3791 different lenses between 2010 and 2066 with expected shifts larger than 0.1 mas between the lensed and unlensed positions of the source. The past events might be interested when analyzing the individual Gaia measurements). 685 of those are expected to happen within the next decade (2021-2031). For 140 events we also expect a magnification between 1 mmag and 0.6 mag.

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:: Estimated distances to 1.33 billion stars in Gaia DR2
Short Name:: gdr2dist scs
Date:: 27 Dec 2024 08:31:05
Publisher:: The GAVO DC team
Description:: This catalogue provides distances estimates (and uncertainties therein) for 1.33 billion stars over the whole sky brighter than about G=20.7. These have been estimated using the parallaxes (and their uncertainties) from Gaia DR2. A Bayesian procedure was used involving a prior with a single parameter L(l,b), which varies smoothly with Galactic longitude and latitude according to a Galaxy model. The posterior is summarized with a point estimate (usually the mode) and a confidence interval (usually the 68% highest density interval). The estimation procedure is described in detail in the `accompanying paper`_, which also analyses the catalogue content. .. _accompanying paper: http://www.mpia.de/homes/calj/gdr2_distances.html

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.
