Notes. Other mutual events of Phobos-Jupiter were identified but are systematically saturated on Jupiter: 2018-08-30, 2018-09-06, 2018-09-30, 2020-01-25, 2020-08-10, and 2022-12-26. This is also observed for Deimos-Jupiter events: 2019-11-29, 2020-02-04, 2020-07-04, 2020-07-08, 2020-09-18, 2020-09-22, 2020-09-25, 2022-02-14. (a)Start and stop time correspond to the time of the beginning and end of the observation sequence. (b)rh is the heliocentric distance of the spacecraft in AU. (c)Δ is the MEX-Jupiter distance. (d)δ is the MEX-Deimos distance. (e)αJ is the phase angle in degrees between the Sun-MEX-Jupiter. (f)αP is the phase angle in degrees between the Sun-MEX-Phobos/Deimos. (g)τ is the exposure time. (h) Some images were discarded and not analyzed because of one of the following reasons: (1) Phobos occults Jupiter or (2) the image is saturated.
