dc.description.abstractWe created a full sky point source catalogue at frequencies around 1 GHz, including the intensity, polarisation, rotation measure and spectral index of the point source. These values were matched to data where available and simulations were used otherwise. With this, we were able to generate full sky intensity and polarisation maps from point sources at the frequencies required for intensity mapping. These are crucial for end to end simulations that take into account the telescope beam effects. We showed that the polarisation intensity at these frequencies is reasonably smooth in frequency, making it easier to clean.
