Apparent sources and possible sources of sunset jets on the nucleus. a) Annotated observation of sunset jets as in Fig. 2h. The apparent sources of jets are marked by green dots. Jets with distinguishable directions are indicated by the dotted blue line and are numbered. b) Oblique view of the source area based on the shape model for illustrating the connections between the apparent source (the green dot), the jet plane (translucent blue plane), and possible sources on the nucleus (the yellow trail) for jet No. 5 in a). The dashed red line indicates the intersection of the jet plane with the nucleus. The solid white line indicates a possible orientation of the jet as reconstructed by connecting the apparent source and a possible source on the surface. c) Determined apparent sources and trails of possible sources on the nucleus of all observed jets in a) with the same viewing geometry. The dashed white arc and the arrows indicate the uplift to the west of the source area. d) Same as c), but with the same viewing geometry as b) to better illustrate the elevation of the apparent sources from the ground as well as the uplift to the west.
