I'm trying to reproduce the results of https://arxiv.org/pdf/1205.1613.pdf where the authors determined the best fit values of the parameters (u,B,c3,c4) in the Massive Gravity action (1)(adsbygoogle = window.adsbygoogle || []).push({});

Using the values they tallied for the best fit parameters as outlined in table I and equations (9), (10), (11) I determined omega lambda, S and Q to be 0.85227,0.0481201,-0.182476 respectively. Using a value of the graviton mass of 2.85*10^-69 kg in table II I calculate u to be 1.16384*10^-23. Using the values of B=.39 c3=2.42 and c4=-2.88 in table II I am unable to obtain using equation (6) the density parameters I calculated above with equation (9), (10) ,(11).This inconsistency make me highly doubt that I am correctly using the BF values to calculate the parameters in the MG action (1). Can anyone of you please help me understand where I am going wrong. Perhaps my value of u is totally off and that is why I'm getting inconsistent results with (6). Any help will be greatly appreciated.
