Measuring $\Delta {\bf t}$

The first step in traveltime tomography is measuring traveltime errors. For a given reference velocity model and reflector geometry, one can calculate traveltimes from each source to each receiver. Then traveltime errors are calculated by comparing the picked event with calculated traveltimes. Therefore, event picking is a prerequisite for measuring traveltime errors.
