Corner plot of the posterior distribution for the RVM parameters for the pulsar geometry obtained using the PA values. Parameters are the PD of radiation escaping from the magnetic pole, pulsar inclination, i_p; magnetic obliquity, θ; position angle, χ_p; and the phase, ϕ₀. 2D contours correspond to 68%, 95% and 99% confidence levels. The histograms show the normalized 1D distribution for a given parameter derived from the posterior samples. The mean value and 1σ confidence levels for the derived parameters are reported above the corresponding histogram.
