Abstract
In the field of seismic prospecting there is an urgent need to minimize the man power of experienced people for drawing a travel time curve of explosion observation. Otherwise the speed of the data accumulation exceeds that of the data processing, and data sit on desks permanently. Here a simple computer oriented method is suggested, which is similar to the method of least squares, but the result is not affected by points far from the straight line which is the true travel time curve.
