1. 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

2. OUSIM interfaces and WPs

4. Interfaces with instrument/SWG/Ous/ST
Documents (included needs, requirements, and tracability)
Data model document
Interface WPs (identified group of people from ST, DM, Instrument, SWG, OUs)
OUSIM products and tasks (WPs)

7. 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 E2E 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.

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

10. 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

11. 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?

12. 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

13. 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

14. OUs simulators OUS simulators
Task: build additionnal inputs for OUSHE, OUPHZ, OUSPE, OULE3, OUMER
Identify the needs 2D 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

15. External data Task: Define external data needed in Ous PANSTARRS DES
Define simulation and products (Image, catalog)
PANSTARRS
DES ….
