Search and download the data from \url{http://archive.eso.org/eso/eso_archive_main.html}. Check only 'HARPS/LaSilla'. For example data select night '2015 07 30' to find data of the asteroid Ceres, use '2004 07 12' and Program ID '072.C-0488(E)' for calibration data taken by the RV exoplanet search team, or use 2010 10 23/25 for HD\,10180 observation. Then download the data (save the download request script, cd to the folder, and run \verb|sh downloadRequest<Number>script.sh|). The raw data (*.fits.Z) can be extracted with:

Few problems occur when comparing the data of reduced with this pipeline and the data from the ESO Phase 3 pipeline:
11421143
\begin{enumerate}\setlength\itemsep{0em}
11431144
\item The bias correction can't be performed, as usually only one bias frame is available.

\item Overscan correction is not implemented in the pipeline.

\item Overscan correction is not implemented in HiFLEx.
11451146
\item No cosmic ray removal is applied.
11461147
\item Different flat fielding.
1147-
\item Traces have a fixed width, therefore the S/N of the extracted data might decrease slightly.
1148-
\item Only one CCD is processed at a time, which might decrease the precision of the wavelength solution.
