Scattering delay variations measurement for PSR J1600–3053 with DR2new. Left plot: 100 random realisations (blue) of the time-domain reconstructions of the scattering delay variations at 1.4 GHz radio frequency modelled as a Gaussian process with DR2new. Independent scattering delays measured from scintillation analysis with the LEAP data (Main et al. 2023) are shown by the black points. Right plot: chromatic index posterior distributions measured for the DM (orange) and the SV (blue) with DR2new, while fixing the chromatic index of the other component. The favoured model for this dataset includes both DM and SV. The black dotted lines emphasise the expected values for DM and SV, respectively at 2 and 4.
