Table A.2
Distance between MEX and the surface measured by MARSIS. These values represent the distance to the point of Phobos that is equidistant from the centres of mass of MEX and Phobos. For an easier use of the data, we can convert those measurements into distances to the centre of mass for both the Willner et al. (2014) and Ernst et al. (2023) shape models using the offset between simulations and MARSIS data (see section 3.1 for more detail). The longitudes and latitudes are taken for the central point of the trajectory for each dataset, and so is the time. The precise moment chosen as time reference is discussed in Appendix B.
