CosmoMC: Parametrization of w

Post by Aurelien Fraisse » February 15 2007

Hi all,

I would like to run MCMCs including the parameters [tex]w_0[/tex] and [tex]w_a[/tex] of the parametrization [tex]w(z) = w_0 + w_a\,(1-a)[/tex]. I could re-invent the wheel, but I'm sure this has already been implemented a number of times. Would anyone know how to do this easily in CosmoMC?

Thanks,
-Aurelien.
