\chapter{Data}
\label{sec:data}
This chapter will explain how the used data was gathered, as well as the criteria for which data was used for the final results. Lastly, I will describe the algorithms used.
\section{Source}
The data used in this thesis was gathered with the help of the astroquery (\cite{astroquery}) python package. For this purpose, as well as displaying the downloaded data, a GUI application was created with the python package PyQt5 (\cite{pyqt5}). The GUI window for downloads can be seen in \ref{fig:download_new_star_data_gui}.

\tablefoot{The star's identifier is given. For the most prominent stars, the name of the star is amended in brackets. The next columns report on the effective temperature and the luminosity of the star in units of the solar luminosity L$_\odot$. The typical uncertainty of the reported temperature and luminosity are 150K and $\sim$10\%, respectively. The top and bottom panel report classification of the clustering. The cluster name refers to the position in the red-giant phase. The literature references are provided in the last column. (Table taken from Elisabeth Höldrich bachelor thesis, 2020)}

\tablefoot{The star's identifier in the \textit{Kepler} Input Catalogue (KIC) is given. Eclipsing systems are marked with an asterisk. The columns $\nu_{\mathrm{max}}$ and $\Delta\nu$ report the frequency of the oscillation power excess and the large frequency separation between radial modes for a given star. $\Delta\Pi_1$ quantifies the true period spacing of dipole modes. The maximum value of the detected rotational splitting $\delta f$ is listed. The evolutionary phase RGB describes H-shell burning red giant. Ambiguous values are marked with '?'. The columns $R$,\,$M$,\,$L$, and $\log g$ report the stellar radius, mass, luminosity, effective temperature and surface gravity from scaling relations, respectively. $T_{\mathrm{eff}}$ was adopted from the KIC. The uncertainties of $\log g$ are on the order of 0.01\,dex and for the temperature typically smaller than 150\,K. $P_{\mathrm{orbit}}$ gives the orbital period from photometry. The column $A$ lists the maximum amplitude of the heartbeat in a rebinned phase diagram. The error estimate for $P_{\mathrm{orbit}}$ and $A$ from the PDM is not reliable due to the remaining contamination of the solar-like oscillations and therefore not given. $|\Delta $RV$|$ reports the maximum difference in radial velocity. Squared brackets mark systems for which the orbital parameters could not yet be determined from radial velocities. \citep[Table taken from][]{Beck2014}}
