Formulas and wavelengths for wavelets used in the paper.

Wavelet	Formula	Period of W(ψ,s) (ps)
Morlet (ω = 2π)	ψ(t) = π−1/4e−t22e2πit	1.01s
Paul (order = 4)	$\psi (t)=8\sqrt{\frac{2}{35\pi }}{(1-it)}^{-5}$	1.389s
Haar	$\psi (t)=\{\begin{array}{cc}1& \hfill -1/2\le t<0,\\ -1& \hfill 0\le t<1/2,\\ 0& \hfill \text{otherwise}.\end{array}$	0.87s
