 Jonathan what would it take to do a test of this?
 
-Ionizing source in media with initially low optical depth but tau builds up till it hits 1.
+Ionizing source in media with initially low optical depth but tau (exp(-tau) ??? ) builds up till it hits 1 (fully ionized??).
 
 We are basically trying to do the strongmen(Stromgren?) sphere problem.
