CLASS Data Products - Circular Polarization Details
CMB circular polarization power spectrum and upper limits presented in https://arxiv.org/abs/1911.00391. The provided product is a single file containing four columns: the bandcenters, the bandpower values for the CLASS 40 GHz VV channel, the 1-sigma uncertainties on the bandpowers, and the 95% C.L. upper limits. The values are in units of μK2CMB. These results are contained in figures 4 and 5 of the paper.
