Thanks for answering that. I am pretty sure it is supposed to have an "n", because otherwise the matching at the boundaries doesn't work. Anyway, that's what's in the VirVubFitter. Now all that remains is my second question, which I have pasted below: (2) The signal function drawn in Figure 4 LOOKS like it has: * x_c ~ 5.28 GeV = 5280 MeV * (alpha*sigma_l) ~ 1 GeV = 1000 MeV * sigma_l ~ sigma_R1, sigma_R2 However, according to Table 7: * x_c = 5.2795 GeV = 5279.5 MeV * (alpha*sigma_l) = 0.000008484 GeV = 0.008484 MeV * sigma_l << sigma_R1, sigma_R2 I tried to check by plotting the function with the given fit parameters in ROOT, but it did not work because ROOT could not handle the exponential of (x - x_c)/sigma_l, since sigma_l is so tiny. Am I missing something, or is there a mistake, or what? Thanks, sheila
