There are several different deadtime contributions that have to be taken
into account during the EPIC pn ODF processing:
one factor depends solely on the readout mode,
the second is related to deadtimes due to discarded CCD columns
because of on-board MIP (Minimum Ionizing Particle) rejection,
the third factor represents additional deadtimes from
MIP rejection per frame per CCD by ground software.
The fourth livetime factor handles the case that not all frames
have been transmitted because of telemetry limits.
Finally, quadrant and CCD specific
deadtimes are caused by the bad frame flagging in epframes.
