Non-Gaussian Likelihoods for Type Ia Supernovae Cosmology: Nested Sampling Chains

The PolyChord outputs from constraining a number of cosmological and scatter models on the Type 1a SNe catalogue Pantheon+. Note: "Uncorrected" refers to redshifts that are not corrected for the peculiar velocities of the SNe, which compared with the default "Gauss". The remainder of the suffixes refer to specific scatter models, detailed in the paper. Also included is the code to generate these outputs, "allchains.py" and "additionaltests.py", as well as an example plot making script "plotmaker.py". This code runs on the Pantheon+ data and covariances, found here: https://github.com/PantheonPlusSH0ES/DataRelease/tree/main/Pantheon%2B_Data/4_DISTANCES_AND_COVAR
