L2 Spacecraft potential (0.2 sec)
is normally the average potential of all available probes, measured relative to
the spacecraft. If all four probes are available, the average is done over all 4 probes. If only two
or three probes are available, the average is done over 2 opposing probes ( P1 and
P, or P3 and P4). If only two non-opposing probes are available (e.g. P2 and P3), this quantity is the
value of one of the probes. If only one probe is available, this quantity is the value of that
probe. The probes used are given by the parameter P_probes. When moderate high-bias
saturation is detected on one of the probes (indicated by bit 14 in the P_bitmask), the average
over 4 seconds is replaced by a maximum over 4 seconds to avoid errors resulting from the
resulting spikes; also the data quality is lowered for such intervals. The
individual probe potentials are available in the ancillary data
