Detailed Description

Auxiliary program to trigger Monte Carlo events.

The options

• -a refers to the detector configuration that is used to convert Monte Carlo true information to raw data; and
• -b refers to the detector configuration that is used to convert raw data to calibrated data.

The event counter of the triggered events, as returned by KM3NETDAQ::JDAQEvent::getCounter(), is set to the corresponding index of the Monte Carlo event in the output.
This allows for correlating the DAQ event to the Monte Carlo event.
The time of the DAQ hits can be correlated to the time of the Monte Carlo hits using the frame index and the time of the Monte Carlo event (Evt::mc_t), respectively (see also time_converter).
The universal time of the DAQ event is set to the universal time of the Monte Carlo event with a correction for the time of the event (read hits) within the time slice.
In run-by-run mode, the trigger parameters as well as the singles rates and status of the PMTs are read from the given raw data file.
The two-fold (and higher) coincidence rates should still be provided on the command line.
