1. GENIUS Kick-Off meeting December 4th 2013 WP-620 Simulated catalogue data Francesc Julbe UB – IEEC, Barcelona

2. Simulation activity for CU9 & GENIUS  Simulations on demand for other CUs  Simulations to validate spectral libraries developed by other CUs  Simulations for CU3 (OR#2)  Simulations of specific objects (SN, Exoplanets,..)  Full Sky simulations for the community with GUMS-10 and GOG-11  Simulations are core component for CU9 development work  All development activity based on simulated data:  ESAC archive design  Data Mining, Science Enabling app and validation software development  Data access and VO (Virtual Observatory) Services  … 2

3.  GOG is a Java tool that generates a simulated GAIA final catalogue.  Astrometric, Photometric, RVS and Astrophysical data (CU3, CU5, CU6 and CU8)  Epoch, BP, RP and RVS  Combined (end-of-mission), BP, RP and RVS  Output format:  Gbin MDB tables according to the MDB definition.  Command line version  Large scale simulations: D istributed environment, scripting needed  Graphical User Interface GOG – Gaia Object Generator 3

4. Simulations  GUMS 10 –Universe Model sources (UM) and their “nominal” values Robin et al. (2012), 2012A&A...543A.100RRobin et al. (2012), 2012A&A...543A.100R  First Data model One single table (GACS), 2.1 billion rows 4

5.  GUMS & GOG-11 –Universe Model data (GUMS-11) ~2.1 billion objects –End of mission: Astrometry, Photometry, RVS and Astrophysical parameters. Simulations II 5

6.  Detailed MDB outputs - Total size: 1.3TB  UM output with ‘nominal values’  MDB/CU3/Agis/Source  MDB/CU5/PhotPipe/Phot/CalPhotSource  MDB/CU6/Source/Source  MDB/CU6/Source/StellarSourceMeanCharacteristics  MDB/CU8/StarParamsPhot Extend (design) a new data model, test technologies available (relational DB?) to coordinate with SAT at ESAC Extend (design) a new data model, test technologies available (relational DB?) to coordinate with SAT at ESAC  Results processed with GAT  Services development  e.g. Data Mining activities Simulations III 6

7.  Future large Scale simulations:  End of mission –End of Mission with updated MDB and outputs –End of mission with BP/RP/RVS  Epoch –Only Epoch parameters –Epoch + BP/RP & RVS  Complete set (Combined + Epoch XP & RVS)  Future custom simulations  e.g. adding systematic errors for validation purposes Simulations IV 7

8.  Readiness to perform large/small scale simulations  Well defined simulation process by the testing team  Consolidated team both in development and in testing  Software (GOG) well adapted to Large Scale simulations  Computing resources available at CESCA (Supercomputing Centre of Catalonia Consortium).
