CosmoMC using Planck l > ~200 only

Post by Elizabeth Gould » February 14 2018

I would like to match a model to the Planck data for only the ls greater than a specific number. While I know how to create an effective cutoff for high ls within CosmoMC, I don't see a way to only match the model to the higher l values. I remember one post indicating that to do this, one must remove the data from the dataset, but the Planck data is not stored in an easy to alter way. I was wondering if anyone knew how to do this, either in the CosomMC code or the Planck dataset.
