NuRadioReco.modules.LOFAR.beamformingDirectionFitter_LOFAR module

NuRadioReco.modules.LOFAR.beamformingDirectionFitter_LOFAR.geometric_delays(ant_positions, sky)

Returns geometric delays in a matrix.

Parameters:

ant_positionsnp.ndarray

The antenna positions to use, formatted as a (nr_of_ant, 3) shaped array.

skynp.ndarray

The unit vector pointing to the arrival direction, in cartesian coordinates.

Returns:

delaysnp.ndarray

class NuRadioReco.modules.LOFAR.beamformingDirectionFitter_LOFAR.beamformingDirectionFitter

Bases: object

Fits the direction per station using interferometry between all the channels with a good enough signal.

Methods

begin(max_iter[, cr_snr, logger_level])	Set the values for the fitting procedures.
run(event, detector)	reconstruct signal arrival direction for all events through beam forming.

end

begin(max_iter, cr_snr=3, logger_level=30)

Set the values for the fitting procedures.

Parameters:

max_iterint

The maximum number of iterations to use during the fitting procedure

cr_snrfloat, default=3

The minimum SNR a channel should have to be considered having a CR signal.

logger_levelint, default=logging.WARNING

The logging level to use for the module.

run(event, detector)

reconstruct signal arrival direction for all events through beam forming. https://arxiv.org/pdf/1009.0345.pdf

Parameters:

event: Event

The event to run the module on

detector: Detector

The detector object
