Abstract
Systematically studying all the RXTE/PCA observations for GRS 1915+105 before November 2010 we have discovered three additional patterns in the relation between QuasiPeriodic Oscillation QPO frequency and photon energy extending earlier outcomes reported by Qu et al Astrophys J 710836 2010 We have confirmed that as QPO frequency increases the relation evolves from the negative correlation to positive one The newly discovered patterns provide new constraints on the QPO models
