Notes. The final four columns list the maximum likelihood values obtained from the data set DR2new, using customised noise models when a common red noise is also included in the recovery model (Antoniadis et al. 2023a). Thus, the missing RN and DM parameters refer to the fact that, according to the customised noise model, there is no relevant evidence for the given process in the EPTA DR2new data set.
