\section{Introduction}
Some stuff here. Very exciting stuff!
\section{Skymap}
Figure \ref{fig:skymap} shows a fake skymap, created by generating Gaussian distributed x-y data:
\begin{equation}
f(x) = \frac{1}{\sqrt{2 \pi \sigma^2}}e^{-\frac{1}{2}(\frac{x-\mu}{\sigma})^2}
\end{equation}
With $\sigma$ the standard deviation and $\mu=0$ the mean.
