Using CosmoMC with PPF module and usew0wa=F
Posted: March 23 2017
Dear Antony,
apologies for what might be a trivial question...
I am trying to use CosmoMC to get constraints on cosmological parameters in the presence of dark energy with a certain equation of state evolving with redshift/scale factor w(a). So in camb/params.ini I set
usew0wa = F
and then supply a file wa.dat with 2 columns: a=1/(1+z), and w(a)
My question is whether CosmoMC supports this type of user-provided dark energy equation of state? I recall reading in this post http://cosmocoffee.info/viewtopic.php?t ... 1bfb015f9f that CosmoMC does not support tabulated w(a) so I was wondering how to get around this
Cheers,
Sunny
