Webused, the Rayleigh wave energy must have propagated through the array and in a direction parallel to the axis of the array. Rayleigh wave energy that propagates parallel to the axis of a linear array will exhibit lower apparent velocities (greater slowness) than energy that propagates through the same array at an angle.
