+Figure 2: Difference between end-of-year fields in the 5-day mean files from the control and the SAS runs.  
+Biggest discrepancies are in the expected places.

+Restartability is still an issue when running SAS, because of the ice model restarting between job segments.
+So a SAS run has been broken down into two segments of 20 days each.  The results at 40 days can then be compared when
+restarting from 20 days (changing nn_date0 accordingly) and when running for the full 40 days. 
+Differences turn out to be identically zero.
