1 Klöckner1 SKADS tools 2 SKA simulation 4 th SKADS Workshop, Lisbon, 2-3 October 2008

2 Klöckner2 SKADS tools 2 SKA simulation 4 th SKADS Workshop, Lisbon, 2-3 October 2008 An inventory of the SKADS tools to a full SKA simulation Hans-Rainer Klöckner

3 Klöckner3 SKADS tools 2 SKA simulation 4 th SKADS Workshop, Lisbon, 2-3 October 2008 What do we want to learn EoR galaxies, clusters Milkyway Ionosphere ? array configuration ?

4 Klöckner4 SKADS tools 2 SKA simulation 4 th SKADS Workshop, Lisbon, 2-3 October 2008 What we (almost) have Catalogues Images NON-SKADS GSM [de Oliveira-Costa et al. 2008] Extragalactic Sources - continuum - HI - polarization (partially) Galactic sources - pulsar (in development) Galactic polarization (e.g. Stokes Q) EoR signal
