Euclid Consortium SGS for OUSIM Meeting goals 1

Euclid Consortium SGS for OUSIM Meeting goals: 1 - Prepare documents for the review process (Mai 2013) : - Define deliverables of OUSIM (code and images) - Define OUSIM input to SWGs group - Agree on input needs from each Ous 2 - Agree on OUSIM data model (used as interface between different groups) 3 - Implementation of prototype =code working in the SGS configuration =>SDC Euclid simu Kick-Off Barcelona 10 July 2012 1

Euclid Consortium OUSIM products OUSIM will manage input and output to satisfy the request from the different groups, allowing specific levels of complexity and size • Official data releases: delivery of final images Programmed simulations increasing in complexity and area. Include all instrument products and final releases should reach large survey area coverage. Entry of E 2 E validation Prototype of implementation + development plan for May 2013 • On demand simulations: delivery and management of codes: Smaller simulations for validation or pipeline development can be run directly by groups or by OUSIM.

Euclid Consortium Top level tasks Use the data model to interface each WPS • Building input source catalogs – identify the needed informations – Identify tools to buid a large mock catalog – list existing catalogs /Ous for dedicatd tests prototype • Building sky simulation – Astrophysical information linked to a field (star, QSO? , …) – Sky models (zodiacal, extinction, cosmic …) prototype – field simulator • Building mission models – survey model – Instrument models (Tel, VIS, NISP) • Building simulators prototypes – pixel level simulator of level 1 data – Other products to simulate level 2 and level 3 data (images and catalogs) (new) Euclid simu Kick-Off Barcelona 10 July 2012 9

Euclid Consortium Source catalogs • Task: provide mock catalogs with galaxies and all needed properties • Library of existing catalogs Task: identify the catalogs needed from each Ous Product: -Prepare a library of existing catalogs -define objects properties for the data model Subgroup = OUs contact. • Build test catalogs… from Nbody. . to mock catalog Task : identify tools to produce the OUSIM input requirements source catalog for large simulation (clustering, lensing. . ) Product: mock prototype(s) : use existing N body catalogs Contact SWGsim Euclid simu Kick-Off Barcelona 10 July 2012 10

Euclid Consortium Building the sky • Sky simulator Task = construction of a representative ‘observed’ EUCLID field • Inputs – Astrophysical models • Zodiacal model • Extinction model • Absorption model – Cosmic simulation – Stars • Product: models for EUCLID field observation simulation • Implementation in the data model of all input/output Prototype? Contact? Survey implementation group? Euclid simu Kick-Off Barcelona 10 July 2012 11

Euclid Consortium Building models • Task : define the mission, the survey and instrument parameters – Mission model -Holds the survey strategy and the operation modes, including calibration. -Should indicate where and how to observe to procure a full sky mock Euclid data set – Instrument models (Tel, VIS, NISP) The instrument groups will be in charge of producing the instrument models: this includes all information as PSF models, thermal models, stray light models and detector models. This will be the input of each pixel simulator and will allow common areas in different channels to converge. • Product: data model description document Euclid simu Kick-Off Barcelona 10 July 2012 12

Euclid Consortium Building pixel simulator • Pixel level simulator Task: build modular pixel level image simulator as realistic as possible – Should use previous instrument models – Should put all instrumental effects (included calibration) • Products : development plan + Algorithms • Short term: • build prototypes: – Identified existing codes that can be used as prototype of image simulator • • • VIS NIP NIS A prototype is a code that pass all the implementation tests in the SDC Euclid simu Kick-Off Barcelona 10 July 2012 13

Euclid Consortium OUs simulators • OUS simulators Task: build additionnal inputs for OUSHE, OUPHZ, OUSPE, OULE 3, OUMER • Identify the needs 2 D image (without calibration) and catalog (parameters, errors. . ) • Identified existing simulator processing and code Products: code to produce catalogs for specific purpose of OU tests. These codes should be also under configuration (SGS implementation) using the data model (tracability) Exmple OUSPE (spectra simulation), OUPHz(magnitude. . ) sub groupe : OUs experts able to produce that simulation Euclid simu Kick-Off Barcelona 10 July 2012 14

Euclid Consortium External data • Task: Define external data needed in Ous – Define simulation and products (Image, catalog) PANSTARRS DES …. Euclid simu Kick-Off Barcelona 10 July 2012 15
