# 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 185 megabytes of memory, and
# 36 cpu seconds on a 1.07GHz PIII laptop.
