\section{Satellite Detection with stvid}
|
|
\label{sec:satellite-detection}
|
|
\index{detect}\index{process}
|
|
|
|
This is a description of \gls{satellite} detection processes.
|
|
To detect \gls{satellite} in a \gls{FITS} file using the \gls{stvid} \gls{toolchain},
|
|
run \texttt{process.py} or, if it exists, the \texttt{process\_new.py}
|
|
\gls{Python} script.
|
|
|
|
Note the \texttt{stvid} application's \texttt{process.py} and \texttt{process\_new.py}
|
|
will perform both the detection and identification steps.
|
|

|
|
|
|
\subsection{\texttt{process\_new.py} Usage}
|
|
\index{process}
|
|
|
|
This assumes you have installed \texttt{\gls{stvid}} as shown in
|
|
section \ref{sec:stvid-setup}, page \pageref{sec:stvid-setup}.
|
|
Adjust the dated directory used in this example to the actual directory name.
|
|
|
|
\begin{minted}{sh}
|
|
cd stvid/
|
|
# Maybe you need to update TLE
|
|
./update_tle.py
|
|
# Process directory
|
|
./process_new.py -c config_new.ini -d data/obs/20220825_1/020502/
|
|
\end{minted}
|
|
\index{process}\index{TLE}\index{config\_new.ini}
|
|
|
|
\subsection{\texttt{process.py} Usage}
|
|
|
|
If there is no \texttt{process\_new.py} it has likely been merged into
|
|
\texttt{process.py}. Or perhaps, to use the ``older'' script it would
|
|
be run as shown below. Note, the old and new configuration files
|
|
are different and should be used with the correct corresponding \gls{Python}
|
|
script.
|
|
|
|
\begin{minted}{sh}
|
|
cd stvid/
|
|
./process.py -c configuration.ini -d data/obs/20220825_1/020502/
|
|
\end{minted}
|
|

Analyze data with applications, such as \gls{AstroImageJ}.
|
|
|
|
\gls{FITS} files are commonly used in astronomy.%
|
|
\footnote{\cite{Wiki22:fitswikipfreeencyc}}
|
|
\gls{AstroImageJ} can read \gls{FITS} format files.
|
|
See

\ref{fig:astroimagej}, page \pageref{fig:astroimagej},
|
|
for a screenshot displaying a \gls{FITS} file generated by
|
|
\texttt{\gls{stvid}}.
