PCA to MAXI mapping. Gray data points are all MAXI orbitwise measurements of Cyg X-1 in the shown energy range. Blue circles represent Γ₁-defined hard states, green intermediate states and red soft states. Black lines define the state cuts. The light blue shaded region corresponds to the hard state in the MAXI HID, the light red shaded region to the soft state, and the region without shading to the intermediate state.
