The BeyondPlanck collaboration recently published the results from mapping out the global Bayesian posterior of instrumental and observational parameters jointly for LFI time-ordered data. These results are the first of their kind, providing an unique new perspective on the calibration process, and in this talk I will share some of the things we learned, and how that can be applied to future...

Accurate cosmological parameters estimates using polarization data put stringent requirements on maps calibration, as highlighted in the recent results of the Planck collaboration. In this talk, I will present the new results of a paper where we point out that a model-dependent determination of polarization calibration parameters can be achieved by the joint fit of the TE and EE CMB power...

A methodology to provide the polarization angle requirements for the different frequency channels of a given CMB B-mode experiment is presented. The component separation procedure used to separate the CMB from the foreground signals is considered in order to establish those requirements. In addition, it is also considered possible instrumental correlations among the different measured...

I will discuss foreground and instrument systematic modeling for upcoming ground-based B-mode searches with the Simons Observatory (SO). I will begin by summarizing the power-spectrum domain foreground and systematic cleaning pipeline for SO. Using this framework we have quantified calibration requirements on bandpass and polarization angle systematics for the SO target of $\sigma_r\approx...
