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