Event classes

Events of simulations and events detected by icecube are stored in instances of SimEvents and RealEvents, respectively. We load some simulated events:

[2]:
events = SimEvents.load_from_h5("multi_test.hdf5")
Resetting rng

Events can span multiple data seasons. For each season, one entry is stored in periods.

[3]:
events._data_periods
[3]:
['IC86_I', 'IC86_II']

The properties of the event are stored as properties. A list of all data fields is accessible through

[4]:
events.keys
[4]:
['true_energy',
 'arrival_energy',
 'reco_energy',
 'ra',
 'dec',
 'ang_err',
 'source_label']

The entries differ for simulated and actual events.

For each period a dictionary of all such data fields is returned by period(p).

[5]:
events.period("IC86_II")

Through the method apply_mask() a mask is applied and a nested dictionary (1st key is period, 2nd key is name of the data field, as returned by keys) is returned containing the selected events. The order of entries in mask needs to be the same as the periods in events.periods. For application, see the notebook on point source analysis.
