Oligomer Size Distributions of Aβ40 and Aβ42 Peptides: Time Averages of the First Moments,${\mu }_1={\overline{N}}_{phot,rel}$, and of the Root of the Second Moments, $\sigma ={\left(\overline{{\left(N_{phot,rel}-{\mu }_1\right)}^2}\right)}^{1/2}$ and ${\mu }_2^{1/2}={\left({\overline{N^2}}_{phot,rel}\right)}^{1/2}$
