  The "Sampling Information" worksheet has been modified to 
  accommodate minor discrepancies between our "best 
  estimate" of eruption dates, as reported in 
  OF2008-1130 v. 1.0, and newly revised values derived 
  through concensus by W. Scott , C. Thornber, and 
  J. Pallister, in consideration of information gleaned 
  during W. Scott's editorial review of Professional Paper 
  1750.
