		# We would really like to give this routine the
		#	options:global
		# attribute, so it only runs on those time levels where
		# we've found (or at least tried to fnid) horizons.  But
		# this doesn't work, because we need a GH -- and the other
		# thorns' routines we call need valid grid variables in it
		# -- in the announcing, and  options:global  routines don't
		# have a "normal" GH, but instead a special one without
		# usual grid variables defined in the usual manner.
		#
		# So, what to do?  The present kludge is to have this
		# routine called on every grid, then have it explicitly
		# test if it's at a horizon-finding time and on a base
		# grid.
