A simple 1-D model, consisting of a low velocity layer covering a homogeneous halfspace, is used to compare the ray-matrix synthetic seismograms with the finite-difference synthetic seismograms. The computation has been carried out according to the history file which contains both the input data and the instructions on program execution. The structure of the history file is discussed in detail, including the comments on the input data.
