High time resolution EXOSAT ME PDS of Cyg X‐1 from the data collected on 1984 July 24 with high time resolution of 0.2 s. Data are fitted by an LF‐HF diffusion model: ﹩\chi ^{2}/ N_{\mathrm{dof}\,}=94.5/ 74=1.27﹩, with the best‐fit parameters ﹩\psi _{\mathrm{cor}\,}=2.48\pm 0.02﹩, ﹩\psi _{D}=1.8\pm 0.3﹩, ﹩t_{0,C}=2.0\pm 0.2﹩ s.
