Abstract

The ray path-wave front chart and similar methods used for vertical shots are briefly described, and the possibility and the advantages of applying the linear time law to these methods is pointed out. A short method of fitting the linear depth law to the observed velocity is described. The possibility of extending any method applicable to verticals to wide shot spreads is shown, and a method of correcting straight path dips for curvature in the case of verticals is pointed out.
