Warning: xe at redshift zero is < 1 in CosmoMC
Posted: August 22 2020
Hi,
I am a novice in CosmoMC and please pardon if it is a trivial question and already answered.
I want to constrain the six parameter [math]CDM model with fsigma8 data given in table: III of https://arxiv.org/abs/1703.10538.
For that, I have written a likelihood similar to bao.f90. When I am using only the fsigma8 data with action = 2, I am getting the minimum values. But when I am using it with action = 0, it is not constraining [math], [math] and [math] well. The contour plots look blotchy even after increasing the range. The code stops with the error
When I am using both Planck 2018 and fsigma8, I am getting nice contours but the error message,
is there.
I understand it is related to CAMB. What is it that I need to take care?
I did not change any parameter value given in CosmoMC May 2020.
Thanks in advance.
