What do we want to learn EoR galaxies, clusters Milkyway Ionosphere array configuration ? ?
What we (almost) have Images Catalogues Galactic sources - pulsar (in development) Galactic polarization (e.g. Stokes Q) EoR signal • Extragalactic Sources • continuum • HI • polarization • (partially) NON-SKADS GSM [de Oliveira-Costa et al. 2008]

Implementation Post-processing enables us to alter/add source properties
