Like its sister instrument Solar Wind and Pickup Ions (SWAPI), the CoDICE instrument collects and  counts two types of particles: ones from the solar wind flowing from the Sun and particles called pick-up ions (PUIs)  that entered the heliosphere from outside our solar neighborhood and traveled inwards where IMAP orbits about a  million miles from the Earth. The solar wind particles CoDICE collects and sorts are highly energized particles,  called suprathermal particles, which are moving faster (and therefore have higher energy) than the solar wind  particles that SWAPI collects. CoDICE also simultaneously measures the velocity, direction of travel, energies,  and types of specific species of PUIs from the local interstellar medium, the interstellar material surrounding our  solar system found directly outside of the heliosphere. Some of these are hydrogen and helium ions like SWAPI,  but CoDICE is also able to collect and analyze heavier ions than SWAPI can.

Propagated from packet-level suspect bit via level 2. 0=good packet group. 1=suspect packet group.

Indicates the energy step when No Scan Operation (NSO) was activated. In NSO, the ESA voltage is set to the first step in the scan and remains fixed until the next cycle boundary.

Indicates the spin sector when No Scan Operation (NSO) was activated. In NSO, the ESA voltage is set to the first step in the scan and remains fixed until the next cycle boundary.

Indicates the half spin when No Scan Operation (NSO) was activated. In NSO, the ESA voltage is set to the first step in the scan and remains fixed until the next cycle boundary.

Energy Step When Reduced Gain Factor Operation (RGFO) was activated

Indicates the energy step when Reduced Gain Factor Operation (RGFO) was activated. In RGFO, the Entrance ESA voltage is reduced in order to limit the number of ions that reach the detectors.

Spin Sector When Reduced Gain Factor Operation (RGFO) was activated

Indicates the spin sector when Reduced Gain Factor Operation (RGFO) was activated. In RGFO, the Entrance ESA voltage is reduced in order to limit the number of ions that reach the detectors.

Half Spin When Reduced Gain Factor Operation (RGFO) was activated

Indicates the half spin when Reduced Gain Factor Operation (RGFO) was activated. In RGFO, the Entrance ESA voltage is reduced in order to limit the number of ions that reach the detectors.

PHA type code. 0 = TCR (Triple Coincidence, STA + STB + SP + APD); 1 = DCR (Double Coincidence, STA + STB + SP); 2 = APD-only energy event (APD with one or two of STA, STB, SP).
