Marginalized posterior probability distributions for the M92 structural parameters and the offset from the gravitational center of M92 (E. Vasiliev & H. Baumgardt 2021). Parameters shown include the central mass density (ρc in 106 M⊙ pc−3), core radius (rc in pc), mass-segregation index of pulsars (αp), and positional offsets from the Gaia-measured center (Δα, Δδ in arcmin). The values shown in the legend are posterior medians with 1σ uncertainties, defined by the 16th–84th percentile range. In the 2D panels, the contours represent the 1σ and 2σ confidence level. The vertical dashed lines in the one-dimensional histograms mark the 16th and 84th percentiles, while the solid pink lines and markers denote the cluster core parameters derived from N-body dynamical modeling (H. Baumgardt & M. Hilker 2018) for comparison.
