Classes

class serendipyty.seismic.input.wavelets.BaseWavelet(*args, **kwargs)[source]¶

Bases: object

Base class for source wavelets.

This is implemented as a function object, so the magic happens in the __call__ member function.

Methods

__call__(self, t=None, nu=None, **kwargs)

__call__(it=None, **kwargs)[source]¶

Callable object method for the seismic sources.

Parameters:	it : int, array-like Index(es) at which to evaluate the wavelet.

__weakref__¶

list of weak references to the object (if defined)

class serendipyty.seismic.input.wavelets.RickerWavelet(t, dt=None, fc=20.0, delay=None, **kwargs)[source]¶

Bases: serendipyty.seismic.input.wavelets.BaseWavelet

Ricker wavelet.

The Ricker wavelet is the negative 2nd derivative of a Gaussian [R13].

Parameters:	t : float, ndarray Time array. fc : float, optional Central (peak) frequency of the wavelet. delay : float, optional Time delay to be applied to the wavelet. The default delay is 1/fc.

Attributes

wavelet

(float, ndarray) Array that contains the wavelet.

Methods

__call__([it])

class serendipyty.seismic.input.wavelets.RickerIntegratedWavelet(t, dt=None, fc=20.0, delay=None, normalized=False, **kwargs)[source]¶

Bases: serendipyty.seismic.input.wavelets.BaseWavelet

Integral of the Ricker wavelet.

This wavelet is the time integral of a Ricker wavelet.

Parameters:	t : float, ndarray Time array. fc : float, optional Central (peak) frequency of the wavelet. normalized : bool, optional Normalize maximum amplitude to 1 delay : float, optional Time delay to be applied to the wavelet. The default delay is 1/fc.
