Update to radc.f : In subroutine lambda_dave, corrected the formula for the proton lambda calculation to agree with formula 59 in PRC 64 054610. Previously, the formula in the subroutine was missing the factor e3/p3. In your simc_gfortran directory you can do cvs update radc.f Cheers, Mark -- Mark Jones 757-269-7733 jones at jlab.org
