Corner plot of the posterior distribution for the RVM parameters for the pulsar geometry obtained using the PA values from the phase-resolved spectro-polarimetric analysis of the combined data. The two-dimensional contours correspond to 68.27%, 95.45%, and 99.73% confidence levels. The histograms show the normalized one-dimensional distribution for each parameter derived from the posterior samples. The mean value and 1σ confidence interval for the derived parameters are presented above the corresponding histogram (dashed lines).
