N2 - Our paper presents new methods for finding and testing weak periodic variability of stellar objects, developed for the purpose of detecting the expected regular light variations of magnetic chemically peculiar (mCP) candidates in the Large Magellanic Cloud. We introduce two new periodograms of the mCP star BS Cir (HD 125630), appropriate for rotating the spotted variables, and compare the results with those obtained by the well-known Lomb–Scargle periodogram. The use of periodograms and testing the significance of the found period candidates are demonstrated with two examples: the observed and simulated observations of the magnetic field of the mCP star CQ UMa (HD 119213) and the mCP candidate OGLE LMC136.7 16501. Three newly developed tests of periodic variability, namely the shuffling, bootstrap, and subsidiary ones, are presented. We demonstrate that the found periodic variations known with the signal-to-noise ratio larger than 6 can be approved to be real.
