- INTA/LAEFF
- Description:
- LAEFF (Laboratory for Space Astrophysics and Theoretical Physics) was founded in 1991 as a collaboration between INTA, CSIC and ESA, and was located at VILSPA to allow for closer interaction with the ESA astronomical activities (IUE, ISO, XMM,...). Research at LAEFF is carried out in different areas of astrophysics, as astroparticle physics, interstellar medium, brown dwarfs and solar, stellar and extragalactic physics. LAEFF is also responsible for the radio astronomical use of the antennas in the Robledo de Chavela station. LAEFF participates in the development of diferent space projects such as OMC-INTEGRAL, EURD, LEGRI and EDDINGTON. LAEFF is also involved in the development and maintenance of Astronomical Data Archives of space missions (INES, OMC) and ground-based telescopes (GAUDI) in the framework of the Virtual Observatory project.

- Title:
- Meudon TITAN code
- Short Name:

- Description:
- TITAN is a computer program for calculating the interactions of a dilute plane-parallel medium with electromagnetic radiation. It includes all atomic processes: absorption, recombination, diffusion, excitation, deexcitation of atoms and ions, heating and cooling of the gas, and it solves the radiation transfer, in order to obtain the spectra reemitted by the medium. It handles plan parallel slabs in non LTE steady state, for various physical conditions and various illuminations, valid in many astrophysical situations. It is specifically designed for warm-hot (8000 to 10**8 K) and thick media (till an electron scattering optical depth of several tens) emitting and absorbing in the X-ray range (density from 10**5 to 10**14 cm-3). It computes the physical parameters, ionisation degrees, temperature, density, and the spectrum of the radiated light in each point of the slab, by solving simultaneously the ionisation equations, the equations of statistical equilibrium, the thermal equations and the radiation transfer, using iteration processes.

- Title:
- MOC - HEALPix Multi-Order Coverage map
- Date:
- 20 Sep 2016 09:45:00
- Publisher:
- IVOA
- Description:
- The Multi-Order Coverage map method (MOC) is dedicated to specify arbitrary sky regions. The goal is to be able to provide a very fast comparison mechanism between coverage maps. The mechanism is based on the HEALPix sky tessellation algorithm. It is essentially a simple way to map regions of the sky into hierarchically grouped predefined cells.

- Observation Data Model Core Components and its Implementation in the Table Access Protocol
- Date:
- 10 May 2017 08:00:00
- Publisher:
- IVOA
- Description:
- This document defines the core components of the Observation data model that are necessary to perform data discovery when querying data centers for astronomical observations of interest. It exposes use-cases to be carried out, explains the model and provides guidelines for its implementation as a data access service based on the Table Access Protocol (TAP). It aims at providing a simple model easy to understand and to implement by data providers that wish to publish their data into the Virtual Observatory. This interface integrates data modeling and data access aspects in a single service and is named ObsTAP. It will be referenced as such in the IVOA registries. In this document, the Observation Data Model Core Components (ObsCoreDM) defines the core components of queryable metadata required for global discovery of observational data. It is meant to allow a single query to be posed to TAP services at multiple sites to perform global data discovery without having to understand the details of the services present at each site. It defines a minimal set of basic metadata and thus allows for a reasonable cost of implementation by data providers. As with most of the VO Data Models, ObsCoreDM makes use of STC, Utypes, Units and UCDs. The ObsCoreDM can be serialized as a VOTable. ObsCoreDM can make reference to more complete data models such as Characterisation DM, Spectrum DM or Simple Spectral Line Data Model (SSLDM). ObsCore shares a large set of common concepts with DataSet Metadata Data Model (Cresitello-Dittmar et al. 2016) which binds together most of the data model concepts from the above models in a comprehensive and more general frame work. This current specification on the contrary provides guidelines for implementing these concepts using the TAP protocol and answering ADQL queries. It is dedicated to global discovery.

- OSA VST ATLAS Survey
- Short Name:
- WFAU OSA TAP
- Date:

- Publisher:
- WFAU, Institute for Astronomy, University of Edinburgh
- Description:
- This service hosts the public releases of the ATLAS Survey housed at the Wide Field Astronomy Unit at the Univeristy of Edinburgh, as well as a number of other external datasets for which WFAU has neighbour tables, that can be cross matched with ATLAS. 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.
