Figure 1Black is sum of derivative, red is integral of fit to
derivative.
The standard deviation in the fit is approximately the same as that in the sum. Neither the fit nor the sum displays any oscillations at large distances. The standard deviation has to do with the probability of finding this same result with a different set of the independent variables.
