520-Definition of problem cases, validation scenarios and tools

  • In VTS document GAIA-C9-SP-OPM-FA-061 ; fields checked for each VTS, some TBDs and question marks removed, VTS WP942-430-040 changed to WP942-430-050, VTS WP942-430-030 divided in VTS WP942-430-030 and VTS WP942-430-040, new VTS WP942-230-010 about binaries (June 2014) - Boudreault
  • Developing codes for VTS ; JUnits using DBTestTable (June 2014) - Boudreault
Line: 71 to 69
 
  • Progress on the technical note on the issue of contamination by bright star GAIA-C9-TN-OPM-SZB-007. Only remain the section on analysis and conclusion (August 2014) - Boudreault
  • Teleconferences on VTS (August 2014) - Antiche, Arenou, Boudreault, Fabricius, Romero-Gomez
Last report from Steve Boudreault : he is leaving his current position at Obs. Paris on 22 August for a position on another project in Göttingen, Germany, starting 1st September.

530-Simulation versus reality: from models to observables

Changed:
<

  • Validation of GAIA data would be performed by comparing it with predictions of the Besancon model. In turn, predictions of Besancon model for various observed quantities e.g. distribution of stars in magnitude bins, colors, proper motion, etc. must be compared with previous observations to confirm the consistency of model with present observations. For this purpose we use IGSL catalogue which is created by combining data from several big astronomical catalogues such as SDSS, MASS2, GSC23, Hipparcos (for bight stars), etc. and compare it with GUMS, the catalogue of mock stars generated according to Besancon model of the Milky Way. Despite the presence of artifacts due to calibrational errors in IGSL, and possible over-estimation in galactic plane and under-estimation of number of stars in high galactic latitude by GUMS, they are grossly in agreement with each other and can be used to verify for GAIA data.

    Furthermore to discriminate between artifacts and real differences of two catalogues we are performing a decomposition to harmonic oscillator. This method allows to discriminate large and small scale structures in the data. Currently we are analysing the results and utility of this method.

  • Developed code for VTS WP944_Val_030_001 and its corresponding JUnit test: proper motions (June 2014) - Ruiz-Dern
  • Rewriting and optimisation of codes done following advices of Nicolas Leclerc and Carine Babusiaux, at Paris Observatory (Meudon site) (June 2014) - Ruiz-Dern, Arenou
  • Teleconference on crossmatch tools and available catalogs (16 June 2014) - Babusiaux, Arenou, Marrese, Giuffrida, Ruiz-Dern
Line: 87 to 82
 
  • CU9 Plenary meeting in Vienna (7-8 July), CU9 Catalogue validation meeting (9 July), and the Gaia data visualisation workshop (9-11 July), all meetings at the University Observatory in Vienna; doubts and issues for WP540 reported, solutions provided for crossmatch tools and database access (July 2014) - Ruiz-Dern, Babusiaux
  • Contact with ESAC to get an update on changes asked in Vienna: commands to crossmatch catalogs in GACS, access to healpix information. Healpix issue still not clearly resolved for us (September2014) - Ruiz-Dern
  • We are waiting for new VOTAP version (being developed by I-Chun at Meudon Observatory) in order to access GACS with credentials (needed for crossmatch purposes with local tables). These two last points are key to continue developing VTS for WP944 (September 2014) - Ruiz-Dern
