pylops.utils.seismicevents.linear2d(x, t, v, t0, theta, amp, wav)[source]

Linear 2D events

Create 2d linear events given propagation velocity, intercept time, angle, and amplitude of each event

x : numpy.ndarray

space axis

t : numpy.ndarray

time axis

v : float

propagation velocity

t0 : tuple or float

intercept time at \(x=0\) of each linear event

theta : tuple or float

angle (in degrees) of each linear event

amp : tuple or float

amplitude of each linear event

wav : numpy.ndarray

wavelet to be applied to data

d : numpy.ndarray

data without wavelet of size \([n_x \times n_t]\)

dwav : numpy.ndarray

data with wavelet of size \([n_x \times n_t]\)


Each event is created using the following relation:

\[t_i(x) = t_{0,i} + p_{x,i} x\]

where \(p_{x,i}=\sin( \theta_i)/v\)
