Three stage period analysis and complementary methods [PDF]
Astronomy and Astrophysics Supplement Series, 1999 We generalize the multistage period search and analysis method for the case when the data error esti- mates (i.e. statistical weights) are available. Adjustment of model parameters allows us to detect complex wave forms in noisy data. Complementary statistical tests are also presented to estimate the significance of the detected periodicities, to ...
