  As is common with the collection of astronomical data, signals are frequently
dominated by noise. However, when performing FTs of light curves, re-binning
data can improve the signal-to-noise ratio (SNR) at lower frequencies. Using
data collected from the Kepler space telescope, we sequentially re-binned data
three times to investigate the SNR improvement of lower frequency (< 17
microHz) variability in white dwarf KIC 8626021. We found that the SNR at
approximately 5.8 microHz greatly improved through this process, and we
postulate that this frequency is linked to the rotation of KIC 8626021.
