T4.3 - Data Mining
Meeting with the active members of the Work PAckage in Madrid (23rd December).
A more detailed work package definition has been done, with an estimate schedule and responsible from 2015 to Spring 2017. This has resulted into a set of 11 WP covering the different aspects of the tasks to perform, from design and implementation point of view to divulgation activities at a later phase.
A Data Mining prototype is being implemented and it's about 70% of its completion. This prototype should be the basis for the future framework.
New cluster has been requested to CSUC which should be in place during February.
Big scientific use case is being studied and its initial prototyping is ongoing using the base technologies selected for this WP (Spark, Hadoop). It will be finished during this year 2015.
T5.2 - Definition of problem cases, validation scenarios and tools
Exploration of potential validation scenarios for TGAS from WP946 (Eyer, Blanco-Cuaresma)
T5.3 - Simulation versus reality: from models to observables
Test and debug of WP943 software and its installation on the ESAC Hudson system (HZ, AR, CR))
Development of a special version of Besancon Galaxy Model for bright stars and generation of mock star catalogues to compare with Tycho data and preparation for TGAS validation (AR and RM)
Development of data analyzing utilities for quantification of validation criteria.
Update of VTS documents according to implementation of test procedures.
Addition of validation procedures relevant for TGAS validation to VTS document and improvement of validation procedures for parallax.
Addition of validation procedures for testing scale-dependent anomalies in the distribution of sources using decomposition to spherical harmonic to VTS documents. Development of software for implementation of these tests is undergoing.
T5.4 - Confronting Gaia to external archives
Adaptation of already developed tests to the new VOTAP, called ValidationTools (December 2014) - Ruiz-Dern, Barache, Babusiaux
Update VTS document to include new and adapted tests for TGAS (December 2014/January 2015) - Arenou, Babusiaux
Tested new "share tables" functionality of v0.5 GACS version, from website and from command-line: not sure if useful in Validation group (January 2015) - Ruiz-Dern, Shih
Discussions with ESAC (Jesús Salgado) and Mantis reported 0031714, due to crossmatch issues with new GACS version 0.5 (January 2015) - Ruiz-Dern
Developed creation of Healpix Maps within VTS WP944_Val_010_001: the test needs to access full Gaia/IGSL catalogue, which is not possible through TAP (January 2015) - Ruiz-Dern
Requested use of gbins instead of TAP for these cases where full catalogue is needed for tests. Working to adapt this option within the ValidationTools (January 2015) - Shih
Changes in ivy.xml of WP944 to have coherent dependencies: ValidationTools must be compiled and added in WP944 classpath when compiling WP944. Therefore, dependencies on ValidationTools are automatically added within the WP classpath. Working to have this safest configuration in both Java platforms NetBeans and Eclipse (January/February 2015) - Babusiaux, Shih, Arenou, Ruiz-Dern
Developing VTS WP944_Val_030_005, Parallax Zero-Point and precision using distant stars, for TGAS (January/February 2015) - Ruiz-Dern
T5.5 - Data demining: outlier analysis
T5.6 - Transversal tools for special objects
600 - Support
T6.2-Simulated Catalogue
T6.3-Science Alerts testbed
700 - Dissemination
T7.1 - Coordination of dissemination activities
T7.2 - Community portal infrastructure
T7.3 - Community portal, outreach and academic activities
