In this example, it appears that flux tubes filled with energetic protons are displacing the ambient particles (data from MIMI/CHEMS: All 3 telescopes included).
This section of the previous plot includes CHEMS/Telescope-2 only, measuring particles with near 90o pitch angle (Cassini is near Saturn’s equator at this time)
Remnants of a previous proton injection that are dispersed only, measuring particles with near 90
This is a section of the plot including data from CHEMS/Telescope-1 only. Here it does not appear that a separate flux tube is displacing the background particles (during this time, T-1 is detecting particles with pitch angles of about 45o).
Another view of these injections from the MIMI/LEMMS sensor only, measuring particles with near 90
A second example showing a dispersed injection detected at the same position by Cassini as new injections at lower energy
While the recent injections in this survey appear to cluster around noon and midnight local time, this is also where Cassini has taken data
