Mass and inclination angle constraints from the DDH PK measurements and the χ² mapping with the DDGR model. The constraints have been derived in the global fit and under the assumption of the Cs noise model (Table 2). Central plots: two-dimensional constraints on the M_c − cos i and M_c − M_p spaces. The solid coloured lines represent the nominal values of the PK parameters, the dashed coloured lines their 1σ limits, and the solid black lines the 1σ and 3σ limits from DDGR. The shaded grey area in the right plot is the region excluded by the mass function (i > 90 deg). Corner plots: marginalised one-dimensional probability densities for M_p, M_c, and cos i from DDGR χ² mapping, showcasing the median value (solid black line) and the 31.4%, 47.4%, and 49.9% percentiles on both sides (shaded areas under the curve).
