+      together with saturation flags for all six waveform channels. The
+      underlying telemetry and waveform samples are otherwise unchanged for

+      conversion to milliamperes, and reports spin phase in the IDEX
+      instrument frame rather than the spacecraft frame.

+      pulser-on message, even when other messages occur between them. This
+      preserves valid pulser transitions that were omitted in Major Version

+      now estimated from the ion-grid-to-target charge ratio, with mass
