Bayesian evidence-driven diagnosis of instrumental systematics for sky-averaged 21-cm cosmology experiments data

Nested sampling posterior samples when a systematic structure is present inside the data. The data is organised in the following way: Folder structure: [likelihood used]/[systematic amplitude]/[type of systematic]/ Result structure: [Noise Model used]_[likelihood used]_sys_[systematic amplitude]_[systematic period]_[systematic phase]_[G21 signal strength] If damped systematic, add _damp at result string. Within the results folder, the "enhance" folder contains the more accurate posterior samples of the enhanced PolyChord run. The third folder [systematicModelled] contains the results when the systematic structure is modelled with the same results string as above.
