A method of accelerated computation of broadband far off boresight patterns of telescope beams is extended and applied to the 100 GHz channels of Planck HFI (HFI 100). Far off boresight angle power patterns are computed with both GRASP PTD and NUIM PO software, considering cuts with an angular size of 10 degrees. The former reveal secondary oscillations of radial power distribution as compared with the latter. The difference for power patterns of a/b polarisation channels is also investigated.

CMB power spectra and cosmological parameters from Planck PR4 with CamSpec
astro-ph.CO 2022-05 accept novelty 3.0

Planck PR4 NPIPE maps processed with CamSpec produce LCDM parameters consistent with 2018 results but with ~10% tighter constraints and shifts toward LCDM values for extensions like Omega_K and A_Lens.
