Notes. Summary of the best-fit statistics for each region of the HID of Cygnus X-1. The table allows for comparison of the constant phase-lag and the constant time-lag models. The fit statistics are given by the total χ2 and number of degrees of freedom (d.o.f.). The number of Lorentzian components used is shown for both the phase-lag and time-lag models.
