  • 0.8 mHz (22 minutes) quasi-periodic oscillation in V404 Cyg corresponds to a transition radius of 104 Rschwarzschild.

  • 1.1 mHz (15 minutes) break frequency in optical part of spectrum in J1118+480. In X-rays, break is at 30 mHz (0.5 minutes). Evidence that break frequency scales with the size of the ADAF region.
