     94Biggest discrepancies are in the expected places.

     97Restartability is still an issue when running SAS, because of the ice model restarting between job segments. 
     98So a SAS run has been broken down into two segments of 20 days each.  The results at 40 days can then be compared when 
     99restarting from 20 days (changing nn_date0 accordingly) and when running for the full 40 days.  
     100Differences turn out to be identically zero.

     146Memory and runtime are both significantly reduced by use of this configuration. 
     147Only four 3D arrays are allocated in this configuration in fld_read, Most of the stp routine is not used.
