The Compact Dual Ion Composition Experiment (CoDICE) will measure the distributions and composition of interstellar pickup ions (PUIs), particles that make it through the heliosheath into the heliosphere. CoDICE also collects and characterizes solar wind ions including the mass and composition of highly energized particles (called suprathermal) from the Sun. CoDICE combines an electrostatic analyzer (ESA) with a Time-Of-Flight versus Energy (TOF / E) subsystem to simultaneously measure the velocity, arrival direction, ionic charge state, and mass of specific species of ions in the LISM. CoDICE also has a path for higher energy particles to skip the ESA but still get measured by the common TOF / E system. These measurements are critical in determining the Local Interstellar Medium (LISM) composition and flow properties, the origin of the enigmatic suprathermal tails on the solar wind distributions and advance understanding of the acceleration of particles in the heliosphere. 

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 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.

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.

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

Quality flag propagated from the packet-level suspect bit for each direct-event priority bin. 0 = good packet group. 1 = suspect packet group. 65535 = fill when no direct-event data are present for the priority bin. 

Time, number of nanoseconds since J2000 with leap seconds included

Lo direct-event telemetry priority level. 0 = SW TCR PUIs, 1 = SW H+, 2 = SW He++, 3 = SW Heavies, 4 = SW DCR PUIs, 5 = NSW Heavies, 6 = NSW H+ and He++, 7 = reserved/unused.
