Automatically Pick Depths For A Layered Velocity Model

Description

Finds depth to boundaries by finding where the travel time curve changes slope. This function has lots of loops, so it is very slow.

Usage

autopick(data, snell = TRUE)

Arguments

data a list containing the following elements:
z:
array of the depths of travel time measurements, in meters.
tt.slant:
array of observed travel time measurements in seconds.
hoffset:
the horizontal offset at the surface from the borehole.
sig:
array of the standard deviation of the travel time measurements normalized to the standard deviation of the best pick. Defaults to 1 if none is given. Used for weighting the travel time measurements in the regression.
snell logical value for if refractions at layer boundaries should be calculated.

Value

numeric array of depth to layer interfaces.
