TL;DR
This paper details the data processing procedures developed by the Kepler Asteroseismic Science Consortium to prepare high-quality light curves for asteroseismic analysis of solar-like stars, addressing issues like outliers, jumps, and drifts.
Contribution
It introduces specific preprocessing methods tailored for Kepler light curves to enhance asteroseismic studies of pulsating stars.
Findings
Effective correction of outliers, jumps, and drifts in Kepler data.
Optimized light curves improve asteroseismic analysis accuracy.
Procedures are applicable to various pulsating star classes.
Abstract
The Kepler mission is providing photometric data of exquisite quality for the asteroseismic study of different classes of pulsating stars. These analyses place particular demands on the pre-processing of the data, over a range of timescales from minutes to months. Here, we describe processing procedures developed by the Kepler Asteroseismic Science Consortium (KASC) to prepare light curves that are optimized for the asteroseismic study of solar-like oscillating stars in which outliers, jumps and drifts are corrected.
