Warning: Rombint failed to converge;

Post by Yazhou Hu » February 05 2015

Hi, everyone. I'm using the July 2014 version of CosmoMC to impose constraints on the CPL dark energy model in the framework of PPF. However I get warnings of the form:

Warning: Rombint failed to converge;
integral, erro, tol: 10378.4046316585 -1.130727759002248E-005
1.0000000000000000E-007

I'm wondering how does this warning affect the constraints? Can anyone help me out here? [/img][/code]

I have the same question. Any answer?

I found a similar question in

http://cosmocoffee.info/viewtopic.php?t=1951

The point is that I have not modified anything in the code: I am just playing with constraints on w0 and wa for the CPL parametrization.

It's probably OK if the error is small, but it may mean you are allowing some parameters to go into strange regions (e.g. varying tau when only using non-CMB data).
