5.3 Source Positions

Obviously, the extraction region will be most effective in maximizing a source's signal and minimizing the background if it is positioned accurately on the source. AE can compute three types of source position estimates:

The responsibility for choosing which position estimate should be adopted for each source is left with the observer.
