Summary of activities Dec 2015 - March 2016

WP1 - Management

  • Amendment sent in Dec. Accepted in Feb 12. CSIC termination, INTA inclusion as a partner
  • 2nd period financial report submitted Feb 17.

WP2 - User community

  • Developement of ideas on the long term preservation of Gaia and related software. Contact made with CU leaders for feedback on feasiblility in different areas. Technical note will be completed once this is recieved in March. (Costigan)
  • Continued assistance in the development of the beta testing of the archive (Costigan).

WP3 - System design

T3.1 Technical Coordination

  • Continuing to liaise between the UEDIN development team and ESAC-SAT (Salgado, Gonzalez, Segovia) to coordinate contribution of GENIUS-developed components to the Gaia Archive Core Systems Interface
  • Liaising with Enrique Solano of INTA (formerly CSIC) in order to define work under WP3 Task 3.3 (VO infrastructure) for recently hired developer

T3.2 Aspects of archive interface design

  • Further contributions to the Gaia CU9 published catalogue data model (definition of indexes/views)

T3.3 VO infrastructure

  • Further contributions to the Gaia CU9 published catalogue data model (refinement of UCD1+)
  • INAF-OATs continued development of VODance:
    • Refactoring TAP code to align with the developing TAP 1.1 draft
    • Refactoring the publishing architecture to a more cloud-based solution
    • fixing an authentication and authorization layer on top of the current TAP implementation

T3.4 Data Centre collaboration

  • UEDIN have created a dynamic ADQL autocomplete library in preparation for inclusion in the GACS interface; now working with ESAC-SAT to integrate in to the GACS system (which employs Google Web Tools)

T3.5 Data mining environments

  • UEDIN have drafted (see dockerpaper.pdf) a paper for Astronomy & Computing concerning use of Docker for iease of containerisation and virtualisation of system components in the context of deployment of components at astronomy Data Centres
  • Continued work on Docker containerisation of DQP and interface components

WP4 - Data Exploitation

T4.2 - Visualization

T4.3 - Data Mining

  • Validation of data conversion tool from ASCII to Parquet to be used in all catalogues to be ingested into the Data Lake
  • Final results on the Grand Challenge Use case (IMF-SFR characterization).
  • Progress meeting at Madrid (UNED premises) with key members of the WP.
  • Definition of specific use cases to be delivered in the GENIUS final report as platform demonstrators
  • General infrastructure with basic services completely set-up.
  • New services being tested.

T4.4 - VO tools and services

WP5 - Validation

T5.1 - Technical coordination

  • telecons with WP managers on Dec. 14 and Feb. 8
  • full participation of main work packages to DR1 rehearsal
  • 11 telecons with GACS for DR1 rehearsal
  • organisation of validation of TGAS_01.00 data

T5.2 - Definition of problem cases, validation scenarios and tools

  • 6 telecons for progress meetings
  • Erika Antiche will leave the project end February, and Sergio Soria will replace her, starting mid January.
  • We have updated our tests to make sure they can run on more than 2000 million sources.
  • We also plan to add new tests to look at the photometric data (magnitude and fluxes).

T5.3 - Simulation versus reality: from models to observables

  • Sékou Diakité is now our of developper in place of Houri Ziaeepour.
  • Paola Di Matteo and Misha Haywood have made progress on other galaxy models for release 2.
  • Improvements in the handling of the output files and scripts to extract latex tables and gnuplot figures done.
  • Tests on new simu from Michalik also done.

T5.4 - Confronting Gaia to external archives

  • New tests for DR1 photometry (hipparcos, HST, colour-colour relations) and TGAS (HST plx, Kepler distances) added.
  • For the rehearsal, direct access to the data allowed early identification of several bugs, both from GACS and from WP944.
  • Documentation started.
  • Run on TGAS 1.0 done and under redaction.
  • APOGEE spectrophotometric distances computed.
  • VBLI proper motion issue understood, cannot be used

T5.5 - Data demining: outlier analysis

  • Two statistical analysis now implemented as VTS_020_100: statistical summery and VTS_02_110: robust multi-parameter analysis
  • Both very created in order to be able to sustain in reasonnable time and resources the management of billion stars
  • Proved very efficient for TGAS_01.00 analysis, though very simple

T5.6 - Transversal tools for special objects

  • Clusters: The proper motion test (010-010) now runs on lists of reference proper motions taken from several catalogues.
  • Clusters: The parallax checks (010-030) are currently performed with photometric distances as references, but we are now looking into using other reference distances.

WP6 - Support

T6.2-Simulated Catalogue

T6.3-Science Alerts testbed

WP7 - Dissemination

T7.1 - Coordination of dissemination activities

T7.2 - Community portal infrastructure

  • Slovenian, Japanese, Macedonian, Croatian and Greek have been added to Gaiaverse during this period. The portal has now 11 languages available on it. In coordination with other project members, who became editors of the Gaiaverse portal as well, the work consisted of setting these languages into the platform by incorporating the translation packages distributed to them.
  • Numbers for Twitter look good. On January 11, this Twitter profile broke the barrier of 250 followers, having now (XXX, 2016) XXX followers. See the evolution below:
    • Dec.15: tweets (13), tweet impression (8,567), profile visits (994), mentions (14), new followers (22), total number of followers on December 2015 (240).
    • Jan.16: tweets (16), tweet impressions (9,791), profile visits (985), mentions (7), new followers (30), total number of followers in January 2016 (270).
    • Feb.16:

T7.3 - Community portal, outreach and academic activities
