classmethod from_dataset(dataset_id, fetch=True, **kwargs)

Load angular resolution from publicly available data.

Dataset_id:: ID date of the dataset e.g. “20181018”
Parameters:: fetch – If true, download dataset if missing

get_reader(): Define an IceCubeAeffReader based on the filename.

get_ret_ang_err(E): Get the median angular resolution for the given Etrue/Ereco, corresponsing to ret_ang_err_p.

property ret_ang_err

sample(Etrue, coord): Sample new ra, dec values given a true energy and direction.

supported_datasets = ['20181018']
