Optical periodicity analysis for radio selected BL Lacertae objects (RBLs).

Abstract (from CDS):
The recently compiled historical lightcurves of 10 RBLs are probed with the Jurkevich method in a search for periodic behaviour. Monte Carlo simulations of artificial lightcurves are used to detect spurious periods and evaluate sources of error in this kind of analysis. Additional analysis based on the discrete correlation function (DCF) provides confirmation for those periods that could have physical significance. We find that periods in the range 1.4-17.85yr are present in nine objects of the sample.
