Solar wind observations collected from Faraday Cup on DSCOVR satellite - unprocessed, full resolution

index of the lower voltage of the HV modulator window (ATBD Table 3.5); each voltage window correlates directly to a proton bulk flow speed

calibration directive exponent (0 = current off, 1 = -14, 2 = -13, 3 = -12, 4 = -11, 5 = -10, 6 = -9)

collector A multiplexor range setting

collector A HV modulation state (0 = on, 1 = off)

calibration directive chain select (0 = apply to all, 1 = only collector chain A, 2 = only chain B, 3 = only chain C)

date and time for each observation

calibration directive multiplier (0 = 3x, 1 = 10x)

calibration directive modulation (0 = off, 1 = on, i.e., in calibration mode)

collector B HV modulation state (0 = on, 1 = off)

collector A analog to digital value

collector B analog to digital value

collector B multiplexor range setting

collector C multiplexor range setting

collector C HV modulation state (0 = on, 1 = off)

One or more measurements were backfilled from the spacecraft recorder and therefore were not available to forecasters in real-time

collector C analog to digital value

One or more measurements were extracted from a packet whose timestamp was older than the threshold at the point of processing

One or more measurements were extracted from a packet whose timestamp was in the future at the point of processing

Loss of proton peak

Fill

Instrument in calibration mode

AOCS non-science mode (spacecraft maneuver/safehold)

Reduced proton data quality; peak identified but resulting science data subject to high uncertainties

Loss of alpha particle peak

Reduced alpha particle data quality; peak identified but resulting science data subject to high uncertainties
