3.3 Using multiple event/apparent horizon finders

It is useful to have multiple event or apparent horizon finders available: Their strengths and weaknesses may complement each other, and the extent of agreement or disagreement between their results can help to estimate the numerical accuracy. For example, Figure 11View Image shows a comparison between the irreducible masses of apparent horizons in a binary black hole coalescence simulation (Alcubierre et al. [5Jump To The Next Citation Point, Figure 4b]), as computed by two different apparent horizon finders in the External LinkCactus toolkit, AHFinder and AHFinderDirect. In this case the two agree to within about 2% for the individual horizons and 0.5% for the common horizon.
