Fine Scale Structure in Cometary Dust Tails - Figure 5.12 - Temporal Map sequence of C/2011 L4's iron tail region as seen by HI-1B with fine-scale difference enhancement

The short extent of this tail means that displaying dust on an axis with fixed ejection time and date proves unsuitable. Dust is therefore shown over a fixed range of ages for each image, i.e. when dust was between 0.1 and 2 days old. As such, the dates and times on the axis are not constant, and fixed points with a specific β_r and t_e move along the axis at the same rate as the cadence of images.
