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.
