QTiling

class gwpy.signal.qtransform.QTiling(

duration: float,

sampling: float,

qrange: tuple[float, float] = (4, 64),

frange: tuple[float, float] = (0, inf),

mismatch: float = 0.2,

)

Bases: QObject

Iterable constructor of QPlane objects.

For a given Q-range, each of the resulting QPlane objects can be iterated over.

Parameters:

durationfloat

The duration of the data to be Q-transformed.

qrangetuple of float

(low, high) pair of Q extrema.

frangetuple of float

(low, high) pair of frequency extrema.

samplingfloat

Sampling rate (in Hertz) of data to be Q-transformed.

mismatchfloat

Maximum fractional mismatch between neighbouring tiles.

Attributes Summary

qs	Array of Q values for this QTiling.
whitening_duration	The recommended data duration required for whitening.

Methods Summary

transform(fseries, **kwargs)

Compute the time-frequency plane at fixed Q with the most significant tile.

Attributes Documentation

qs

Array of Q values for this QTiling.

whitening_duration

The recommended data duration required for whitening.

Methods Documentation

transform(fseries: FrequencySeries, **kwargs) → tuple[QGram, float]

Compute the time-frequency plane at fixed Q with the most significant tile.

Parameters:

fseriesFrequencySeries

The complex FFT of a time-series data set.

kwargs

Other keyword arguments to pass to QPlane.transform.

Returns:

outQGram

Signal energies over the time-frequency plane containing the most significant tile.

farfloat

Crudely estimated false alarm rate (FAR) for the detected signal.
