  You have completed the reproduction pipeline and are ready to configure
  and implement it for your own research. This template reproduction
  pipeline and document contains almost all the elements that you will need
  in a research project containing the downloading of raw data, processing
  it, including them in plots and report, including this abstract, figures
  and bibliography. If you use this pipeline in your work, don't forget to
  add a notice to clearly let the readers know that your work is
  reproducible. If this pipeline proves useful in your research, please
  cite \citet{ai15}.

\section{Congratulations!}
Congratulations on running the reproduction pipeline! You can now follow
the checklist in the \texttt{README.md} file to customize this pipeline to
your exciting research project.

Just don't forget to \emph{never} use numbers or fixed strings (for example
database urls like \url{\wfpctwourl}) directly within your \LaTeX{}
source. Read them directly from your configuration files or outputs of the
programs as part of the reproduction pipeline and import them into \LaTeX{}
as macros through the \texttt{tex/pipeline.tex} file. See the several
examples within the pipeline for a demonstration. For some recent
real-world examples, the reproduction pipelines for Sections 4 and 7.3 of
\citet{bacon17} are available at
\href{https://doi.org/10.5281/zenodo.1164774}{zenodo.1164774}\footnote{\url{https://gitlab.com/makhlaghi/muse-udf-origin-only-hst-magnitudes}},
or
\href{https://doi.org/10.5281/zenodo.1163746}{zenodo.1163746}\footnote{\url{https://gitlab.com/makhlaghi/muse-udf-photometry-astrometry}}. Working
in this way, will let you focus clearly on your science and not have to
worry about fixing this or that number/name in the text.

Figure \ref{delete-me} shows a simple plot as a demonstration of creating
plots within \LaTeX{} (using the {\small PGFP}lots package). The minimum
value in this distribution is $\deletememin$, and $\deletememax$ is the
maximum. Take a look into the \LaTeX{} source and you'll see these numbers
are actually macros that were calculated from the same dataset (they will
change if the dataset, or function that produced it, changes).

The individual {\small PDF} file of Figure \ref{delete-me} is available
under the \texttt{tex/build/tikz/} directory of your build directory. You
can use this PDF file in other contexts (for example in slides showing your
progress or after publishing the work). If you want to directly use the
{\small PDF} file in the figure without having to let {\small T}i{\small
  KZ} decide if it should be remade or not, you can also comment the
\texttt{makepdf} macro at the top of this \LaTeX{} source file.

\begin{figure}[t]
  \includetikz{delete-me}

  \captionof{figure}{\label{delete-me} A very basic $X^2$ plot for
    demonstration.}
\end{figure}

Figure \ref{delete-me-demo} is another demonstration of showing images
(datasets) using PGFPlots. It shows a small crop of an image from the
Wide-Field Planetary Camera 2, on board the Hubble Space Telescope from
1993 to 2009. This cropped image is one of the sample FITS files from the
FITS file standard
webpage\footnote{\url{https://fits.gsfc.nasa.gov/fits_samples.html}}. Just
as another basic reporting of measurements on this dataset within the paper
without using numbers in the \LaTeX{} source, the mean is
$\deletemewfpctwomean$ and the median is $\deletemewfpctwomedian$. The
skewness in the histogram of Figure \ref{delete-me-demo}(b) explains this
difference between the mean and median. The dataset was prepared for
demonstration here with Gnuastro's \textsf{Convert\-Type} program and the
histogram and basic statstics were generated with Gnuastro's
\textsf{Statistics} program.

{\small PGFP}lots\footnote{\url{https://ctan.org/pkg/pgfplots}} is a great
tool to build the plots within \LaTeX{} and removes the necessity to add
further dependencies (to create the plots) to your reproduction
pipeline. There are high-level language libraries like Matplotlib which
also generate plots. However, the problem is that they require many
dependencies (Python, Numpy and etc). Installing these dependencies from
source, is not easy and will harm the reproducibility of your paper. Note
that after several years, the binary files of these high-level libraries,
that you easily install today, will no longer be available in common
repositories. Therefore building the libraries from source is the only
option to reproduce your results.

Furthermore, since {\small PGFP}lots is built by \LaTeX{} it respects all
the properties of your text (for example line width and fonts and
etc). Therefore the final plot blends in your paper much more nicely. It
also has a wonderful
manual\footnote{\url{http://mirrors.ctan.org/graphics/pgf/contrib/pgfplots/doc/pgfplots.pdf}}.

This pipeline also defines two \LaTeX{} macros that allow you to mark text
within your document as \emph{new} and \emph{notes}. For example, \new{this
  text has been marked as \texttt{new}.} \tonote{While this one is marked
  as \texttt{tonote}.} If you comment the line (by adding a `\texttt{\%}'
at the start of the line or simply deleting the line) that defines
\texttt{highlightchanges}, then the one that was marked \texttt{new} will
become black (totally blend in with the rest of the text) and the one
marked \texttt{tonote} will not be in the final PDF. You can thus use
\texttt{highlightchanges} to easily make copies of your research for
existing coauthors (who are just interested in the new parts or notes) and
new co-authors (who don't want to be distracted by these issues in their
first time reading).

    webpage, kept as examples for this file format. (b) Histogram of pixel

\section{Notice and citations}
To encourage other scientists to publish similarly reproducible papers,
please add a notice close to the start of your paper or in the end of the
abstract clearly mentioning that your work is fully reproducible.

For the time being, we haven't written a specific paper only for this
reproduction pipeline, so until then, we would be grateful if you could
cite the first paper that used the first version of this pipeline:
\citet{ai15}.

After publication, don't forget to upload all the necessary data, software
source code and the reproduction pipeline to a long-lasting host like
Zenodo (\url{https://zenodo.org}).
