Agradecimentos: The ETH Zurich Cosmology group acknowledges support by grants 200021_192243 and 200021_169130 of the Swiss National Science Foundation. Some of the results in this paper have been derived using the healpy and HEALPix packages. In this study, we made use of the functionalities provided by numpy (Walt, Colbert & Varoquaux 2011), scipy (Virtanen et al. 2020), matplotlib (Hunter 2007), scikit-learn (Pedregosa et al. 2011), PolyChord. We thank Antony Lewis for the distribution of GetDist, on which we relied to produce some of the plots presented in this work (Lewis 2019). We would also like to thank Uwe Schmitt from ETH Zürich for his support with the GitLab server and CI engine.
