 \item A regular matrix of rectangular pixels is defined via \parameter{coordinates = cartesian}. This is the default option.
 \item A matrix of rectangular pixels containing columns and/or rows with double sized pixels, resembling a silicon pixel detector module with several readout chips, can be defined via \parameter{cartesian_module}. The following parameters can additionally be set to configure such a detector:
   \begin{itemize}
-  \item The matrix \parameter{big_pixel} lists the columns and rows with double sized pixels. The following example describes a sensor with 52 x 80 pixels and larger pixels in the left, right and upper edges:
