BASE AND TOP CALCULATION DETAILS

The base and top are designed to emulate results in the past obtained from persistence plots. In

general, the top was calculated by examining the most intense region near the top of a waveform

in an eye-pattern persistence map. The AORM package improves on this in that the tops of all

pits are calculated independently: rogue amplitude variations in the waveform can be identified.

The waveform in the next figure contains two pits. We need only consider the first of these.
