Figure 6. (a) The timeline for A0030206014 generated from MPS 198 shows that the exposure began as the source emerged from earth occultation. The satellite was moving toward the source during the first half of the observation (increasing limb angle), then away from the source as the limb angle decreased again.

(b) The projected component of the satellite's velocity projected in direction of the source during exposure A0030206014. The velocity is positive when the satellite is moving toward the source.
