Median projection of the temporal cubes for the different dates reduced with the PIC pipeline (Berdeu et al. 2020). The fitted orbits are projected on the different dates: S1 in red, S2 in green, and S3 in blue. The arrows indicate the projected motion direction. The dashed circles indicate the median fitted moon position during the acquisitions at each date. The central part of the field of view has been replaced by a dimmer deconvolved image of Elektra to simultaneously visualise the primary and the moons.
