Procedure

This vignetting of the RGA is effective for $\beta>\beta_{\rm vig}$. The transmission of the RGA has the following parameterization:


\begin{displaymath}F(\beta) = \left \{ \begin{array}[h]{cl} 1 & ,\ {\rm for}\ \... ...a} & ,\ {\rm for}\ \beta > \beta_{\rm vig} \end{array}\right. \end{displaymath}

Emiprical Corrections of these values are provided in the table RGA_SELFVIGNCORR in CCF QuantumEf (section 4.4.17). After interpolation of this table, the analytical function be multiplied my these correction factors.
