HL-sims
The PSM or Planck Sky model is an updated version (using knowledge derived from Planck observations) of the software tool described in [Ref to the PSM paper of 2012]. This can take in actual band-passes (in a RIMO) and create sky maps and catalogues at the specified frequencies
The Level S (LS in short) is a generic simulation tool common to HFI and LFI. One version was described in ref to the old LS paper. It can take in input the output of the PSM, a poiting and beam description and it creates the infalling power on detectors. It can addionnaly create some noise realisation as a very simplified version of the actual instruments.
The PSM together with the LS form two basic bricks of a more extensive instrument specific simulation environment. For HFI, see HFI-Validation#sims.
