ACE Radiation Data

ACE Data Table.

ACE radiation data are plotted around periods when science runs were interrupted. Plots start exactly 2 days before the interruption started. The top panel shows differential fluxes of electrons 38-53 and 175-315 (particles/cm2-s-ster-MeV), the middle panel shows differential fluxes of protons 47-65, 112-187, and 310-580 (particles/cm2-s-ster-MeV).

Two vertical red lines indicate the start and the end of the interruption. Purple hatched areas indicate that the satellite is in the radiation belt. The horizontal dashed line indicates P3 trigger level. If P3 level is higher than this level more than 2 hours, SCS 107 may be manually triggered.

Two vertical red lines indicate the start and the end of the interruption. Purple hatched areas indicate that the satellite is in the radiation belt. The red horizontal dashedline indicates SCS 107 limits. If the HRC shield rate/256 goes above 248, automatic SCS 107 is triggered.
