Research direction

Start by reading issues 13 and 14, then locate the notebook for cosmological constraints on the cosmoDC2 dark matter halo catalog. Trace how the CCL backend is used for binned and unbinned cluster abundance. Done means the likelihood and covariance-estimation modules are implemented and the notebook demonstrates binned cluster-count abundance.

Written by the indexing model from the issue text.

Description

Compilation of issue/13 and issue/14, implementation of:

  • cluster abundance prediction with CCL (binned & unbinned),
  • likelihood module,
  • module for covariance matrix estimation,

To edit a notebook that shows cosmological constraints with cosmoDC2 dark matter halo catalog, using binned cluster count abundance with CCL backend.
