Query: A modified version of the Gregory-Loredo method for Bayesian periodic
  signal detection   The detection of planetary transits in stellar photometric light-curves is
poised to become the main method for finding substantial numbers of terrestrial
planets. The French-European mission COROT (foreseen for launch in 2005) will
perform the first search on a limited number of stars, and larger missions
Eddington (from ESA) and Kepler (from NASA) are planned for launch in 2007.
Transit signals from terrestrial planets are small (Delta_F/F approx 10^{-4}),
short (Delta_t approx 10 hours) dips, which repeat with periodicity of a few
months, in time series lasting up to a few years. The reliable and automated
detection of such signals in large numbers of light curves affected by
different sources of noise is a statistical and computational challenge. We
present a novel algorithm based on a Bayesian approach. The algorithm is based
on the Gregory-Loredo method originally developed for the detection of pulsars
in X-ray data. In the present paper the algorithm is presented, and its
performance on simulated data sets dominated by photon noise is explored. In an
upcoming paper the influence of additional noise sources (such as stellar
activity) will be discussed.
