Nonlinear Least Squares Location
Nonlinear Least Squares Location using Gieger's method
initial guess for event location
This is an adaptation of non-linear least squares inversion for earthquake location. A residual function is supplied, and iterations are performed until the location is determined.
vector, new location
At this stage there are no weighting mechanisms or code to eliminate data that has residuals that are too large.
