### Getdist: values in the .margestats file

Posted:

**March 09 2005**Hi,

I am using the COSMOMC code to obtain constraints on cosmological parameters and GETDIST to analise the output files. I have been comparing my results with the outputs from other code and the results for simple six parameter models agree quite well in general, but with some subtleties. I have a doubt about what do the values quoted in the .margestats file really mean. I have interpreted those values as the mean value, the standard deviation, and the limits of the allowed regions for the parameters correspondent to the values given by the parameters "contour1" and "contour2" in the distparams.ini file (by default 68% and 95%). Is that correct?

I will also like to know the precise definition of the limits, that is: how are they calculated?

I hope you can help me. Thanks in advance
