DES Y3 likelihood update for CosmoMC?

Post by Hanyu Zhang » December 21 2022

Hi,

I am trying to combine my likelihoods with the most recent WL likelihood from DES Y3 using CosmoMC. CosmoMC seems to provide DES Y1 instead of DES Y3. Is there any plan for an update? If I want to build it myself, will that be straightforward? I deep-dived a little bit, and Y3 seems to have more nuisance parameters than Y1.

Thanks,
Hanyu

I don't think it's straightforward. There's a Cobaya interface (using some other codes) at
