Should the multiplication symbol after the S&E in Fig. 3 of the paper be omitted?

[dvorst]

Should the multiplication symbol after the S&E in Fig. 3 of the paper be omitted? Equation (5) of the paper does not contain this multiplication but it does contain a +1. In the code however, this is commented out
