Notes. All positions are given relative to the observation phase centre. The log Bayes factor (ln𝒦) is relative to the model with the highest evidence. M10 kpc is not a free parameter, but is computed from the MULTINEST chains. The Ms definition is described in Eq. (4). Positions are given relative to the phase centre (J2000 09:03:11.61 +00:39:06.70) and angles are defined east of north. Parameter definitions follow the Code-independent Organised Lens Standard (Galan et al. 2023). An extended version of this table is presented in Table A.1.
