NuRadioReco.detector.generic_detector module

class NuRadioReco.detector.generic_detector.GenericDetector(*args, **kwargs)[source]

Bases: DetectorBase

Used the same way as the main detector class, but works with incomplete detector descriptions. The user can define a default station. If any property is missing from one of the other station, the value from the default station will be used instead. If no channels are specified for a station, the channels from the default station will be used instead. For cases when the station design has a lot of channels, a default channel can also be defined. The default channel has to be part of the default station. It works the same way as the default station: Any property missing from one of the other channels will be taken from the default channel. The GenericDetector also ignores commission and decommission times and should therefore not be used for real data, but only for simulation studies. This detector only accepts json detector descriptions or dictionary.

antenna_by_depth: Getter function for the antenna_by_depth attribute
