Methods Documentation

__call__(event: ctapipe.containers.ArrayEventContainer) → None

Event-wise prediction for the EventSource-Loop.

Fills the event.dl2.tel[tel_id].disp[prefix] container and event.dl2.tel[tel_id].geometry[prefix] container.

Parameters

event: ArrayEventContainer

fit(key, table)

Create and fit new models for key using the data in table.

predict_table(key, table: astropy.table.table.Table) → Dict[ctapipe.reco.reconstructor.ReconstructionProperty, astropy.table.table.Table]

Predict on a table of events

Parameters

tableTable

Table of features

Returns

disp_tableTable

Table with disp predictions, matches the corresponding container definition

altaz_tableTable

Table with resulting predictions of horizontal coordinates

classmethod read(path, **kwargs)

Read a joblib-pickled reconstructor from path

Parameters

pathstr or pathlib.Path

Path to a Reconstructor instance pickled using joblib

parentNone or Component or Tool

Attach a new parent to the loaded class, this will properly

subarraySubarrayDescription

Attach a new subarray to the loaded reconstructor A warning will be raised if the telescope types of the subarray stored in the pickled class do not match with the provided subarray.

**kwargs are set on the loaded instance

Returns

Reconstructor instance loaded from file

write(path, overwrite=False)
