SUMMARY:Search for weak periodic signals buried in noisy time series using 
 modern Bayesian methods: secondary eclipses in Kepler light curves
DESCRIPTION:Search for weak periodic signals buried in noisy time series us
 ing modern Bayesian methods: secondary eclipses in Kepler light curves\nDr
 . Hannu Parviainen\n\nDetection and characterisation of weak periodic sign
 als from noisy time series is a common problem in many different fields of
  astrophysics. Here I detail one approach for testing whether a signal wit
 h roughly known characteristics exists in the data, using a search of seco
 ndary eclipses from Kepler-observed photometric time series as an example.
  The method is based on Bayesian model selection and uses Gaussian process
 es to model the stochastic variability in the data in non-parametric fashi
 on.
