Studying photometric time series in the frequency domain can serve as a means\nof detecting rotational modulations, measuring asteroseismic modes and even\ndetecting short-period transiting planets. To our knowledge, there is no prior\narchive of the NASA Kepler Mission's power spectra and so we present one here\nto aid the community in searching for such effects. Using DR25 PDC long-cadence\nKepler photometry, 2,594,616 individual periodograms are computed using Welch's\nmethod with a Nuttall window, where we provide a unique periododogram for each\nquarter (up to 16) of each star (196,791 in total). Additionally, we normalize\nthe periodograms in the high-frequency end and combine them into channel- and\nquarter-averaged power spectra to track common instrumental modes occurring\nonboard the telescope, with a particularly notable feature at ~80 minutes (~200\n\μHz) observed.\n
