Detailed Description

Structure for smooth point source.

Stores number of wavelet samples at simulation sample rate, start index for source action, source location information (cell index, position in cell), sampling order, and buoyancy values near source, along with the wavelet time series (at simulation sample rate). Wavelet is either (i) read from file, or (ii) extracted from target pulse, read from file, or (iii)Gaussian with zero, min, or max phase, producing a propagating Ricker pulse in 3D.

Source function for the pressure equation: - (r) v0(r,t) Source function for the velocity equations: - (r) p0(r,t), where p0, v0, are the slns of the homogeneous acoustic problem given by eqns. (5) and (8) in the tech report by WWS

phi = 1 for r < rad, phi = gauss(phipeak, rad) for r >= rad.

Therefore, phi(r) = x phi'(r) / r and phi'(r) = - 2 * phipeak^2 * pi^2 * (r - rad) * exp(-phipeak^2 * pi^2 * (r - rad)^2 );
