Corner plot of the posterior distributions inferred from the GSN 069 QPE timing data. The sampled parameters are ﹩p[{M}_{\bullet }],\,e,\,\cos {\theta }_{{\rm{\min }}},\,{q}_{r,{\rm{ini}}},\,{q}_{z,{\rm{ini}}},\,{q}_{\phi ,{\rm{ini}}},\,{T}_{{\rm{obt}}}[{\rm{\sec }}],﹩ a, ﹩{\dot{T}}_{{\rm{obt}}},\,{{ \mathcal A }}_{0}[{M}_{\bullet }],\,\omega [{M}_{\bullet }^{-1}],\,{\rm{\Delta }}{{\rm{\Phi }}}_{0},\,{\theta }_{{\rm{obs}},{\rm{eff}}},\,{\sigma }_{{\rm{sys}}}[{\rm{\sec }}]﹩. The parameters ﹩{{ \mathcal A }}_{0}﹩, ω, and ΔΦ₀ characterize the SMBHB-induced time modulation.
