Precise description of the Tasks
Definition, implementation and validation of the algorithms to compute Luminosity and Stellar Mass Functions for : Deep and wide Euclid photometric galaxy survey Deep and wide Euclid spectroscopic galaxy survey
Definition, implementation and validation of the algorithms to compute selection functions for : Deep and wide Euclid photometric galaxy survey Deep and wide Euclid spectroscopic galaxy survey
Questions: Are we also in charge of angular selection functions ? Are we in charge of selection functions for external (DES, PanStar)
photometric galaxy survey ? It is not done by OU-EXT or WP external data?
Are we in charge of selection functions for others catalogues such as stars, clusters… ? Or is it done by the cluster of galaxies WP…

Problem of Man Power
Do we have enough man power in the WP? More people in the validation part than in the
implementation part. Small number of persons involved in the WP▪ Among those, postdocs cannot make long term
commitments. How many FTE are needed ? (WPBD = 4.2
FTE ?) Do we have enough expert to complete all
the tasks__

Problem of WP outputs = definition and coordination =
Requirements on the algorithms from SWG ▪ From Galaxy clustering SWG, Weak Lensing
SWG, Galaxy evolution SWG Requirements on the algorithms from
OULE3 WPs ?▪ From Galaxy Clustering WP, Clusters of galaxies
WP, Weak Lensing WP, Time domain WP

WP inputs = definition and coordination =
Who is in charge of computing luminosities and stellar masses, and other quantities we need (e.g. galaxy types, k-corrections…) ? Photometric survey: OU-PHZ Spectroscopic survey: OU-SPE
Who is in charge of generating the mock catalogues with these derived quantities to develop and test the algorithms ? OU-SIM? OU-PHZ? OU-SPE?

Need of coordination
Need of coordination
Codes available
Inventory of existing codes: For LFs and SMFs :▪ Public: M. Bolzonella ▪ Not (yet) public: ALF (O. Ilbert, E. Zucca, L. Tresse)▪ Not public: L. Pozzetti
Angular Selection Functions :▪ Public: Mangle (M. Swanson)
Test the validity of current implementations Agree with WP constraints or requirements Will be sufficiently accurate for a survey like
