+    \begin{itemize}
+	\item it is best to test your newly written thorn against some known data
+	\item for this the example implementation contains an extra routine that provides a made up binary where the position of the neutron stars are given by a Gaussian blob
+	\begin{align}
+		\rho(r) &= A \exp(-r^2/(2\sigma^2)) \\
+		R(t) &= R_{\text{max}} + (R_{\text{max}} - R_{\text{min}})\,\cos(2\pi/T_r) \\
+		\phi(t) &= 2\pi t/T_\phi + \phi_0 \\
+		x(t) &= \pm R(t) \cos \phi(t) \text{ for right/left blob} \\
+		y(t) &= \pm R(t) \sin \phi(t) \\
+		r(t) &= \sqrt{x^2(t)+y^2(t)}
+	\end{align}
+	\item controlled by a parameter \texttt{add\_moving\_blobs}. Check \texttt{param.ccl} for possible options and \texttt{src/moving\_blobs.c} for the code.
