             abstract = "New time-series analysis tools are needed in disciplines as 
                         diverse as astronomy, economics, and meteorology. In particular, 
                         the increasing rate of data collection at multiple wavelengths 
                         requires new approaches able to handle these data. The 
                         panchromatic correlated indices K^{(s)}_{(fi)} and L^{(s)}_{(pfc)} 
                         are adapted to quantify the smoothness of a phased light-curve 
                         resulting in new period-finding methods applicable to single- and 
                         multiband data. Simulations and observational data are used to 
                         test our approach. The results were used to establish an 
                         analytical equation for the amplitude of the noise in the 
                         periodogram for different false alarm probability values, to 
                         determine the dependency on the signal-to-noise ratio, and to 
                         calculate the yield rate for the different methods. The proposed 
                         method has similar efficiency to that found for the string length 
                         period method. The effectiveness of the panchromatic and 
                         flux-independent period finding methods in single as well as 
                         multiple wavebands that share a fundamental frequency is also 
                         demonstrated in real and simulated data.",
