Two ROSINA DFMS m∕Q = 44 Da/e spectra top and bottom, measured on 31 July 2015 during and after the slew, 16:29:55 (MC_20150731_162827570_M0222.TAB, row B) and 17:13:15 UTC (MC_20150731_171147603_M0222.TAB, row B), at off-nadir angles 130 and 19 degrees, respectively. ²⁸SiO and CS cannot be separated and have been fitted as a single peak indicated by the red dashed line (dotted lines: all other species, solid line: sum curve; see Sect. 3 for information on the peak shape). The contribution to CS by fragmentation of cometary parent CS₂ → CS is indicated by the red shaded area and may fully account for the measured signal. The bottom panel also contains the sum curve of the upper panel obtained during the slew for comparison.
