EVENT TIME -
Event time given in year, day of year,
hours and minutes in the general form: yyyy-dddThh:mm.
CHANNELTRON EVENT FLAG -
A flag denoting that an event may be
defined by a channeltron signal, in which case the flag is set to 1,
otherwise it is set to 0.
ION EVENT FLAG -
A flag denoting that an event may be
defined by an ion signal, in which case the flag is set to 1,
otherwise it is set to 0.
ELECTRON EVENT FLAG -
A flag denoting that an event may be
defined by an electron signal, in which case the flag is set to 1,
otherwise it is set to 0.
ION COLLECTOR THRESHOLD -
Code (ICP) corresponding to the
threshold set for the positive ion charge impulse(Q_I) at the time of
impact.
ELECTRON COLLECTOR THRESHOLD -
Code (ECP) corresponding to the
threshold set for the electron charge impulse (Q_E) arising from an
impact.
CHANNELTRON THRESHOLD -
Code (CCP) corresponding to the
threshold set for the channeltron charge (Q_C) impulse arising from an
impact.
ENTRANCE GRID THRESHOLD -
Code (PCP) corresponding to the
threshold set for the entrance grid charge impulse (Q_P) at the time of
impact separately for positively and negatively charged particles.
CHANNELTRON VOLTAGE LEVEL -
Code (HV) corresponding to the
channeltron high voltage level(HV) set at the time of impact with
integers representing fixed voltage differences.
See Channeltron Voltage Level,
Confidence Level Note.
TIME ERROR FLAG -
Flag indicating the time error to be
assigned to each impact.
DDS STATUS NOTE -
Note concerning DDS or Galileo
spacecraft status.
