Parameters in each of the eight HIS priority levels defining the behavior of the onboard ion event priority scheme as flown from January to June 2022.
| Priority range | Ions | Event word | Event word | Event word |

| 3 | C4+ – C6+ | 400 | 116 250 | 3494 |
| N5+ – N6+ | ||||
| O5+, O7+ – O8+ | ||||
| 4 | O6+ | 100 | 2500 | 199 |
| 5 | He2+ | 100 | 5000 | 598 |
| H+ (> 5 keV e−1) | ||||
| 6 | H+ (< 5 keV e−1) | 100 | 10 000 | 598 |

Notes. The first column lists the designation of each priority range, the second column lists the associated ion species, the third column lists the input limit for the maximum allowed number of event words per elevation step, the fourth column lists the event buffer storage size limit in event words per complete scan onboard the spacecraft, and the fifth column lists the telemetry sample size limit in event words per complete scan for downlink to the ground. Each subsequent priority level may receive additional allowed event words for downlink in a given scan if the previous level has not saturated its telemetry sample limit.
