Data and observation handling (gammapy.data)¶
Introduction¶
gammapy.data currently contains the EventList class,
as well as classes for IACT data and observation handling.
Getting Started¶
You can use the EventList class to load gamma-ray event lists:
>>> from gammapy.data import EventListDataset
>>> filename = '$GAMMAPY_EXTRA/datasets/vela_region/events_vela.fits'
>>> events = EventListDataset.read(filename)
TODO: events.info() gives s KeyError: 'ONTIME'.
Should we introduce a sub-class EventListIACT?
>>> from gammapy.data import EventListDataset
>>> filename = '$GAMMAPY_EXTRA/datasets/hess-crab4-hd-hap-prod2/run023400-023599/run023523/hess_events_023523.fits.gz'
>>> events = EventListDataset.read(filename)
>>> events.info()
