epexposure (epexposure-0.16) [xmmsas_20230412_1735-21.0.0]
If there is a difference between the NEPDH counter (see Table 1),
giving info on the number of events which have been transmitted from the
Event Analyser [EPEA] to the Data Handling Unit [EPDH]) and the number of
raw events in the corresponding time interval in
all active CCDs for this quadrant then the interval associated with
these raw events
has to be considered as bad (handled via GTI creation)
Both frame counters have to be computed over the time interval
of 
CYCLEs from the quadrant under consideration.
