Montepython likelihood for DESI2024-BAO and SN-pantheonplus,union3,desy5
The original likelihood and data can be found in cobaya
https://github.com/CobayaSampler/cobaya/blob/master/cobaya/likelihoods/sn/pantheonplus.py
https://github.com/CobayaSampler/bao_data/tree/master
If you want to specify the tracers included in your analysis, you can do the setting like
desi_2024_gaussian_bao_all.exclude = ['LRG1','LRG2']
By default, we include all the tracers.
We would appreciate it if you cite our work
