Locating the event horizon in a generic 3D numerical spacetime is quite complicated and a lot of work (you need to trace null rays backwards in time, which means reading the metric from 3D Cactus-format data files). If the data is 1D, then it is much simpler to use a method adapted to 1D, which would mean using something other than the Einstein Toolkit. For example, it may be possible to do this in Mathematica, Matlab, or similar, or even directly in Python.
Does someone have a suggestion for where Maitraya could look for numerical tools for doing this in 1D?
