Alpha particle temperature average sample count below threshold
solar wind alpha speed
Alpha particle peak height exceeds expected threshold
Proton temperature average sample count below threshold
Alpha particle peak identified above the expected position
Proton temperature value out of expected range
Proton velocity X component in GSE coordinates value out of expected range
Out of range: low - the proton peak current occurred in the first window of the measurement cycle.
Out of range: unknown - no measurements in this cycle exceeded the noise threshold.
solar wind alpha density
Normal operation mode (full sweep)
Unresolved proton peak, peak band consists of fewer than 3 voltage windows
Likely alpha particle confusion due to non-negligible alpha particle flux which may have contributed to currents measured in the proton peak range. Threshold defined as the two peaks being within two thermal widths of each other.
Out of range: high - the proton peak current occurred in the last window of the measurement cycle.
One or more measurements were backfilled from the spacecraft recorder and therefore were not available to forecasters in real-time
One or more measurements were extracted from a packet whose timestamp was in the future at the point of processing
One or more measurements were extracted from a packet whose timestamp was older than the threshold at the point of processing

Alpha particle peak identified below the expected position
Alpha particle peak identified but not bounded by <10% current values
Out of range: unknown - no measurements in this cycle to the right of the proton peak exceeded the noise threshold.
Out of range: high - the alpha particle peak current occurred in the last window of the measurement cycle.
