Notes. Columns 3–6 give the amplitude of the SLF variability, its characteristic frequency, the roll-off slope in logarithmic scale, and the white noise level. Columns 7–8 provide the goodness of fit through the reduced χ2 and probability Q. Typically, a fit is considered to be good if χred2 ≈ 1 or Q > 0.001.
