Parameter Forecast for Future CMB Experiments with COSMOMC

Here we review the changes one should include in the public code CosmoMC (by Antony Lewis), as well as other ingredients necessary for performing a cosmological error forecast based on future CMB experiments (including optionally lensing extraction, through the quadratic estimator technique). All explanations are detailed in the documentation [doc], which refers to the following codes:

- NEW (Nov. 2009 ) updated for compatibility with recent version of CosmoMC: download

- the code FuturCMB consists in a few Fortran 90 files grouped in FUTURCMB.tar.gz

- the modified subroutines ReadAllExact and ChiSqExact, available as a text file, should be inserted inside the public version of cmbdata.f90

We applied such a prescription to perform a parameter sensitivity forecast for future CMB experiment in this ref.

You can also look at a related discussion (not including CMB lensing, though) in the CosmoCoffee forum.
