Velocity Analysis

The third variation is accessed through the Rickvel script. It displays CMP gathers in the left display, a semblance panel at the given CMP location, and the NMO corrected gather (Figure 7). It lets you pick the velocity function on the semblance panel and automatically updates the NMO panel. When you quit Rickvel, it outputs the RMS velocity function.
