 # We support searching for up to N_horizons distinct apparent horizons
-# (some of which may be nested inside others) in a slice.  We number
-# these 1, 2, 3, ... (this seems a bit more user-friendly than Cactus's
-# native 0-origin numbering).  Since Cactus arrays are 0-origin, we
-# make the arrays be of size N_horizons+1, and don't use the [0] array
-# elements.
+# (some of which may be nested inside others) in a slice.
+# IMPORTANT: The horizons are numbered 1 to N_horizons.

 # To change the N_horizons limit, just change the upper limit for
 # N_horizons itself, change all the [N_horizons+1] array sizes in this
