Triangular plot of the posterior distributions for the noise parameters included in the TempoNest analysis of PSR J2205+6012. The parameters EFAC1, EQUAD1, and EFAC2 on the one hand and EQUAD2 on the other shown in log-space refer to the Effelsberg and NRT data, respectively. The last four parameters are the amplitude and spectral indices for the TN (A_TN, γ_TN) and DM (A_DM, γ_DM), respectively. A_TN and A_DM are also shown in log-space. The set of EFAC and EQUAD parameters shows no evidence of systematic errors in our TOA uncertainties. While the DM noise is well constrained, the TN remains unconstrained with our eight-year dataset.
