2. The amplitude-weighted mean TOA and DOA are computed from the times and angles <strong>of</strong> all<br />
remaining hits. These values are then used as the TOA and DOA for the beam (see<br />
Figure Chapter 4 - -19). The amplitude <strong>of</strong> the beam is computed by a simple mean.<br />
