Two selection statistics are used to extract new candidate periodic variables from the epoch photometry of the Hipparcos catalogue. The primary selection criterion is a signal-to-noise ratio. The dependence of this statistic on the number of observations is calibrated using about 30 000 randomly permuted Hipparcos data sets. A significance level of 0.1 per cent is used to extract a first batch of candidate variables. The second criterion requires that the optimal frequency be unaffected if the data are de-trended by low-order polynomials. We find 2675 new candidate periodic variables, of which the majority (2082) are from the Hipparcos 'unsolved' variables. Potential problems with the interpretation of the data (e.g. aliasing) are discussed.

- Evolutionary state of magnetic chemically peculiar stars (2006, methodology): “Information on the rotation periods of the magnetic stars in our sample was obtained from the catalogue of Catalano & Renson (1998) and was further supplemented with the period measurements reported in several recent studies (Paunzen & Maitzen 1998; Koen & Eyer 2002; Ryabchikova et al. 2005).”
