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 |
