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. When the instrument is off, the flag is set to X, and when the setting is unknown, the flag is set to '?'.

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. When the instrument is off, the flag is set to X, and when the setting is unknown, the flag is set to '?'.

ION COLLECTOR THRESHOLD - Code (ICP) corresponding to the threshold set for the positive ion charge impulse(Q_I) at the time of impact.
