The FACT telescope is a Cherenkov telescope on the island of La Palma. This set of tools is dedicated to read, parse and process raw data produced by the FACT telescope.

The newest version!

This processor calculates the photon charge by the following procedure:
\begin{enumerate}
\item Use the {\ttfamily MaxAmplitude} processor to find the maximum
  value in the slices ({\em maxAmplitude}).
\item In the area between {\em amplitudePosition} and {\em
    amplitudePosition} - 25, search for the position having 0.5 times
  the original {\em maxAmplitude} value. This reveals a slice index
  {\em halfMaxPos}.
\item Sum up all slices between {\em halfMaxPos} and {\em halfMaxPos +
    30}.
\item Divide the sum by the {\em integralGain} and store the result.
\end{enumerate}
Treatment of edge cases is currently very arbitrarily affected, since
pixels with these values should not be considered {\em shower pixels}
anyways.
