This code provides various supernova likelihoods, with and without calibration.
Usage
To use any of these likelihoods, simply mention them in the likelihoods block
(e.g. sn.pantheonplus
), or add them
using the input generator.
Installation
This likelihood can be installed automatically as explained in Installing cosmological codes and data.
