Top: typical pre-inbound-equinox (29–30 September 2014) southern hemisphere time variation of the seven studied species for a time period analyzed in Luspay-Kuti et al. (2015). The signal has beenscaled to the distance of Rosetta from the center of the nucleus (i.e., multiplied by r²). Species that trend together are illustrated with empty and filled markers. Bottom: corresponding sub-spacecraft longitude (red) and latitude (black). Errors are smaller than the marker size. Plot shown for comparative purposes with post-outbound-equinox data.
