 Thorn {\tt IDBrillData} provides three choices for the $q$ function: 
 an exponential form, ({\tt IDBrillData::q\_function = "exp"})
 \begin{equation}
-q = a \; \frac{\rho^{2+b}}{r^2} \left( \frac{z}{\sigma_z} \right)^2
-e^{-(\rho - \rho_0^2)} \left[ 1 + d \frac{\rho^m}{1 + e \rho^m}
+q = a \; \frac{\rho^{2+b}}{r^2} e^{-\left( \frac{z}{\sigma_z} \right)^2}
+e^{-(\rho - \rho_0)^2} \left[ 1 + d \frac{\rho^m}{1 + e \rho^m}
 \cos^2 \left( n \phi + \phi_0 \right) \right]
 \end{equation}
 a generalized form of the $q$ function first written down by Eppley
