Solar Energetic Particle Fluences					
April 15, 2001 Event					
Based on Data from ACE/EPAM; GOES-8,11,&12; and SAMPEX/PET					
					
Note: Statistical Uncertainties on GOES and EPAM data are negligible.					
To account for systematic uncertainties in combining data from different					
   sensors we add 20% in quadrature with the statistical uncertainties
