Longitude and latitude covered along the bound orbits phase at 30, 20, and 10 km orbit radius (left panel) and Rosetta orbits reported in the 67P body-centered solar orbital (CSO) frame (right panel). The CSO frames for 67P are defined as follows: X-axis points from 67P to the Sun; the Y-axis is the component orthogonal to the X-axis of inertially referenced velocity of the Sun relative to 67P; the Z-axis is X cross Y, completing the right-handed reference frame.
