Abstract

COMBINE is an add-on to SIGSPEC and CINDERELLA. A SIGSPEC result file or a file generated by CINDERELLA contains the significant sinusoidal signal components in a time series. In this file, COMBINE checks one frequency after the other for being a linear combination of previously examined frequencies. If this attempt fails, the corresponding frequency is considered ``genuine''. Only genuine frequencies are used to form linear combinations subsequently. A purely heuristic model is employed to assign a reliability to each linear combination and to justify whether to consider a frequency genuine or a linear combination.
