* square root of the mean power level around 0.2 mHz, the Fourier transform being normalized by 2/T with T the effective duration of the observational time series. For some objects, different reduction procedures were available. In this case, the value given within brackets refers to more sophisticated data reduction (using weighted FT or polynomial correction at low frequency), while the other value refers to classical procedure.
