Abstract
We 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.
