The BeyondPlanck collaboration has implemented the first integrated Bayesian end-to-end analysis pipeline for CMB experiments with its primary focus being on processing the LFI data. The Cosmoglobe project is a natural generalization of BeyondPlanck whose long-term goal is to include all the available datasets to completely cover the entire sky in radio, microwave, and sub-millimeter experiments. Such ambitious goal requires broad participation from the CMB community; thus, making the idea of Open Science and reproducibility the two foundational aspects of this program.
Therefore, in my talk, I am going to discuss our efforts towards this aim. In particular, what we did in order to facilitate the easy code and data distribution, code-documentation, compilation procedures etc. In addition, I am going to describe our efforts on code and algorithm validation, for which we have generated the a set of 1 year LFI 30 GHz simulated data with known inputs. Finally, I will discuss the difference between frequentist and Bayesian simulations and their different applications in model testing and parameter estimation.
