  • Writing Mantis issues 0027618 (June 2014) - Boudreault
  • Teleconferences on VTS (June 2014) - Antiche, Arenou, Boudreault, Fabricius, Romero-Gomez

  • In VTS document GAIA-C9-SP-OPM-FA-061 ; moving some text from the "Objectives" section to the "Procedure" section for the VTS in WP942, and some rewriting done in "Input data (with errors) used for tests" for several VTS in WP942 (July 2014) - Boudreault
  • Developing codes for VTS ; some rewriting of codes done following the recommendation of Nicolas Leclerc, a colleague at Paris Observatory, Meudon site (July 2014) - Arenou, Boudreault
  • Summer student (Clément Viard) working on the bright stars issue, under the supervision of SB and FA. Figures done and analysis under way. These analysis will be presented in the technical note in preparation on the issue of contamination by bright star GAIA-C9-TN-OPM-SZB-007 (July 2014) - Arenou, Boudreault, Viard
  • Writing Mantis issues 0028517 (July 2014) - Boudreault
  • Teleconferences on VTS (July 2014) - Antiche, Arenou, Boudreault, Fabricius, Romero-Gomez
  • 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 (July 2014) - Boudreault

  • In VTS document GAIA-C9-SP-OPM-FA-061 ; informations added in the procedure sections of the VTS to better describe the Java codes (August 2014) - Boudreault
  • Developing codes for VTS ; WP942-220-020 was created, although it is also in a preliminary state such as WP942-220-010. However, informations on the way the verifications should be done are given in the code (August 2014) - Boudreault
  • Conversion from the IGSL catalogue in GEPI from radian to degree for alpha and delta : the modification was done in the codes and the corresponding JUnits, and also in the two test database (August 2014) - Boudreault, Shih
  • Following the conversion from radian to degree for the IGSL catalogue at GEPI, the software tool Hudson send an error message concerning the JUnit test for the VTS WP942-110-030, which gets the minimum and maximum values for alpha and delta from the Data Model for IGSL. Since these values are still in radian (e.g. 0 < alpha < 2*pi), the JUnit fail (i.e. expecting 0 < alpha < 360). A mantis was reopen about this issue (see mantis #0025775). As long as the Data Model for IGSL remains in radian, Hudson will send an error for WP942 for the JUnit of VTS WP942-110-030 (August 2014) - Boudreault
  • Summer student (Clément Viard) working on the bright stars issue, under the supervision of SB and FA. Figures done and analysis under way.

530-Simulation versus reality: from models to observables

  • 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.

  • 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
