Cosmomc : how can I generate a dense contour map?

[Nao Suzuki]

Hello all,

I would like to make a nice contour plot with 1, 2, 3 sigma contours. Probably, this is not what MCMC is meant to be, but is there any way
I can increase the number of realizations for dense contour purpose?

Thank you in advance for your thoughts.

Just generate more samples, e.g. by stringent convergence test on the tails like this:

Code: Select all

MPI_Check_Limit_Converge = T
MPI_Limit_Converge = 0.01
MPI_Limit_Converge_Err = 0.2

Maybe also increase the temperature if you really need to get 3sigma contours accurately.
