Some of Rosetta’s orbital parameters and the signal strength of the studied CS₂ isotopologues in the vicinity of comet 67P in March 2016. Top : signal strength in arbitrary units. Middle : sub-spacecraft (solid line) and sub-solar (dashed line) latitudes. Bottom : heliocentric (dashed line) distance of 67P and cometocentric distance (solid line) between 67P and the Rosetta spacecraft. The shaded region represents the time period studied in this paper.
