# This parameter file sets up Misner initial data and finds the
# apparent horizons in it with AHFinderDirect.
#
# Note that the grid is very high-resolution, but small (the outer
# boundaries are very close in). This isn't a problem for the purposes
# of this test. This run takes about 213 megabytes of memory on my laptop.
