Deprojected coordinates of LSB-D derived from orbit catalogues following the methodology of Oman et al. (2021) as detailed in Sec. 3.1. The grayscale map shows a histogram of the deprojected coordinates for simulated satellites with projected coordinates, host mass and satellite mass compatible with those of LSB-D. The red lines mark the median and 16^th-84^th percentiles of the marginalised probability distributions for the deprojected radius r_3D and current speed v_3D.
