There are some irregularities near the edge of the map that may come from the shooting region being too small. In fact, increasing the shooting region size does get rid of the "holes" at the edges. A 5\% increase seems to do it, though this hasn't been robustly checked for all cases. As it stands, the shooting region size is determined by,  \begin{equation}  xr_{\rm x_{\rm  img} = 1.05 \times xr_{\rm x_{\rm  tar}/|1 - \kappa - \gamma| \\ yr_{\rm y_{\rm  img} = 1.05 \times yr_{\rm y_{\rm  tar}/|1 - \kappa + \gamma|. \end{equation}  Here's an example:
