Compile literature constraints on CMASS NGC and a baseline P(k) inference

[maho3]

The goal here is to compile a list of previous inferences on the CMASS NGC dataset, for eventual use in an Introduction or Discussion section.

Also, we would like to generate a relevant baseline inference posterior with which to compare against our models. This could be done either by:

• Running a simple observational inference with a baseline emlulator and a Gaussian likelihood.
• Contact the authors of existing papers for their posterior samples.

Mikahil has kindly offered to send us these chains, or run new ones for us with custom priors. We should decide at the next ltu-ili meeting what priors we would like for this first version, so we can send him a request.
