Proposed Schedule and Key Issues

By February 15^th:

Survey design + science goals for AGNs, galaxies and clusters separately

Examine two extreme survey configurations:

50 deg2 with 40 ks exposures

200 deg2 with 10 ks exposures

Critical underlying questions are:

how to best use the LSS information ? Do we need one or two areas ?

how to determine cluster masses to 10% accuracy? Down to which mass (stacking)?

impact of selection effects in the cosmological modelling
=> define requirements for the associated S-Z and lensing surveys

how to best determine SEDs for galaxies and AGNs ?
=> define requirements for the associated optical and IR surveys

which specifications for a deep LSS follow-up spectroscopic survey?

February 15^th - March 15^th:

Merge the requirements

Select sky areas

Define future associated surveys, if necessary
