Timestamp in Event and in Object

1

Hello experts,

For my understanding so far, the Events in Corryvreckan are written down depending on their start and stop time. In the event I can “put” some objects, having teir timestamp too.
I am wondering, how the timestamp of the object is treated w.r.t. the event timing.
For exmple:
if the event starts at 5 ns and end at 20 ns, and I put a pixel with timestamp 7 ns, will it be 7 ns after the start of the event or will it be 7 ns starting from 0? Meaning, will it be at 7ns overall or at 12 ns overall?

Thank you!
Elena

Hi @esidoret

timestamps are always “absolute”, so they count from the beginning of the run, not per-event. Your pixel timestamp will be at 7ns total, so 2ns into the current event (7ns - 5ns).
