Disk models (i.e. M31-like models, including the model based on M31 iteself) are disfavored relative to our COP model or the simple isotropic case.}  \end{table*}  In order to gain insight as to whether the data presented in Figures \ref{fig:zoom} and \ref{fig:full} does indeed argue for the existence of coherently rotating satellite structures, we compare the SDSS data to mock observations of simple, idealized "toy" models of satellite systems. These models are not intended to give detailed descriptions of satellite phase space distributions or physical behavior. Rather, we treat them as simple test cases to which the data can be compared. We begin by detailing how each toy model is constructed:  \begin{enumerate}
