Moment-Tensor Amplitude modelling and inversion

This class acts as an abstract interface for users to perform moment-tensor modelling of far-field amplitudes

Parameters:

xnumpy.ndarray: X-axis
ynumpy.ndarray: Y-axis
znumpy.ndarray: Z-axis
recsnumpy.ndarray: Receiver locations of size \(3 \times n_r\)
velnumpy.ndarray: Velocity model of size \(n_x \times n_y \times n_z\)
src_idxnumpy.ndarray: Source location indices (relative to x, y, and z axes)
comp_idxint: Index of component at receiver side
omega_pfloat: Central frequency of source
cosine_sourceanglesnumpy.ndarray, optional: Cosine source angles of size \(3 \times n_r \times n_x \times n_y \times n_z\)
distsnumpy.ndarray: Distances of size \(\times n_r \times n_x \times n_y \times n_z\), optional
