By-event parameters

Mandatory

EVENT_ID type: int64

Event identification number at the DL3 level. See notes on EVENT_ID

• As only a int64 is possible and event identification in KM3NeT contains various subparts, a conversion function between the identifiers and our internal identification is necessary.
• Identifier parts (19 digits available):
  • instrument (1 digit): i - 1 km3net, 2 antares
  • detector_id (3 digits): ddd
  • run_id (6 digits): rrrrrr
  • frame_index (6 digits): ffffff
  • trigger_counter (3 digits): ttt encoded id: idddrrrrrrffffffttt

TIME type: float64, unit: s

Event time (see Time: https://gamma-astro-data-formats.readthedocs.io/en/v0.2/general/time.html#time)

• KM3NeT: unix time from event time + track time

RA type: float, unit: deg

Reconstructed event Right Ascension (see RA / DEC: https://gamma-astro-data-formats.readthedocs.io/en/v0.2/general/coordinates.html#coords-radec ).

DEC type: float, unit: deg

Reconstructed event Declination (see RA / DEC: https://gamma-astro-data-formats.readthedocs.io/en/v0.2/general/coordinates.html#coords-radec ).

ENERGY type: float, unit: TeV

Reconstructed event energy

• In KM3NeT: given in GeV
