Restrictions on the parameters M and a given by the RP, RP1, and RP2 models due to the QPO data simultaneously observed in the microquasar GRO J1655-40. The solid lines are given by the 3νL ~ 2νU twin HF QPOs resonance, while the dashed lines are obtained for the nodal frequency νnod that explains the LF QPOs at the same r3:2 radius. The crossing of the twin HF QPO and the LF QPO limits implies the mass and spin of the black hole. The optical mass limit is shaded.
