Image Details
Caption: Figure 11.
A comparison of Z σ (blue empty crosses) and ∣S∣ (orange empty circles) for a series of images capturing a variable star (eclipsing binary). The measured LAST magnitude of the star (green solid circles) is also shown, with its value on the right y-axis. For a stationary variable star, ∣S∣ is dominant.
