- Description:
- AAVSO Photometric All-Sky Survey (APASS), underway since 2010, covers the entire sky from 7.5 < V < 16.5 magnitude, and in the BVugrizY bandpasses. A northern and a southern site are used, each with twin ASA 20cm astrographs and Apogee Aspen CG16m cameras, covering 2.9x2.9 square degrees with 2.6arcsec pixels. Landolt and SDSS standards are used for all-sky solutions, with typical 0.02mag calibration errors on the bright end. Data Release 10 is a complete reprocessing of all 500K images taken with the system, including hundreds of nights not part of DR9. Sextractor is used for star finding and centroiding; DAOPHOT is used for aperture photometry; the astrometry.net plate-solving library is used for basic astrometry, supplanted with more precise WCS that utilizes knowledge of the optical train distortions. With these changes, DR10 includes many more stars than prior releases. More information is available at http://www.aavso.org/apass.

- Publisher:
- The GAVO DC team
- 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.

- Adding catalog data to object lists using the VO
- Date:

- Publisher:
- The GAVO DC team
- Description:
- This brief tutorial shows you how to quickly add proper motions and photometry from Gaia to (almost) any object list using the Virtual Observatory. The VO protocol most suited to this kind of this is TAP ("table access protocol") and lets you transfer data and queries to database servers. In the example, we will be using TOPCAT as a client. There is no lock-in to it: There are libraries and other tools allowing an integration of TAP operations into arbitrary workflows – that's what standards are about. Tutorial supplements apply the techniques to Simbad, show how to use TAP from Python, and introduce UCDs.

- Short Name:
- am lensing 2
- Date:
- 23 Mar 2022 13:13:04
- 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.

- 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.

A fairly powerful one is the Web Interface to the Relational Registry (WIRR for short) at http://dc.g-vo.org/WIRR To actually speak to the VO services discovered, clients speaking the service's protocols are still required. In this tutorial, Topcat plays that role. Starting from a simple use case, we work up to investigating the Tully-Fisher relation in different bands using independently discovered resources.

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.

- Date:

- Publisher:
- The GAVO DC team
- Description:
- Brown dwarfs are objects occupying the gap between the least massive stars and the most massive planets. They are intrinsically faint objects so their detection is not straighforward and, in fact, was almost impossible until the advent of global surveys at deep optical and near-infrared bands like SDSS, 2MASS or DENIS among others. We propose here to mine the 2MASS-PSC and SDSS-DR9 databases to identify T-type brown dwarfs through an appropriate combination of colours in the optical and the infra-red, an approach that perfectly fits into the Virtual Observatory.

- 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

- 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).

- Description:
- A plain positional crossmatch service that allows file and URL uploads to be crossmatched to DC-internal tables. In general, you want to use TAP for this kind of thing when it is available, but in a pinch it might come in handy. Larger catalogues that can be matched against include 2MASS, USNO-B, PPMX, CARS, and more.

- Publisher:
- The GAVO DC team
- Description:
- We estimate the distance from the Sun to sources in Gaia eDR3 that have parallaxes. We provide two types of distance estimate, together with their corresponding asymmetric uncertainties, using Bayesian posterior density functions that we sample for each source. Our prior is based on a detailed model of the 3D spatial, colour, and magnitude distribution of stars in our Galaxy that includes a 3D map of interstellar extinction. The first type of distance estimate is purely geometric, in that it only makes use of the Gaia parallax and parallax uncertainty. This uses a direction-dependent distance prior derived from our Galaxy model. The second type of distance estimate is photogeometric: in addition to parallax it also uses the source's G-band magnitude and BP-RP colour. This type of estimate uses the geometric prior together with a direction-dependent and colour-dependent prior on the absolute magnitude of the star. Our distance estimate and uncertainties are quantiles, so are invariant under logarithmic transformations. This means that our median estimate of the distance can be used to give the median estimate of the distance modulus, and likewise for the uncertainties.

- Description:
- 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 http://svn.ari.uni-heidelberg.de/svn/gavo/hdinputs/ivoidval.

- Description:
- The global TAP schema collects information on tables and columns from known TAP servers. This facilitates locating queriable data by physics (via UCD) or keywords (via description). Note that this shouldn't really be necessary as all information present here should be exposed through Registry records. However, in reality data providers currently are much more liable to give column metadata in their tap_schema than in their Registry records. Hence, for the time being, we maintain this service by harvesting tap_schemas about monthly.

- 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.

- Description:
- Operators of publishing registries can use this service to request a re-harvest of their registry by pasting in their registry's IVOID below. If you paste in the magic value ``ivo://ivoa.net/rofr``, we will also fetch new registries from the RofR. You usually want to use this when you want to see the effect of some change in your registry on, say, TOPCAT. Note that you cannot start a full re-harvest of a registry from this interface. Contact the operators if you think you need that.
