Similar patterns of behavior are shown in the next two examples. The overview for H 1743–322 (Figure 7, panels b–g) shows many state transitions (panel b), and the complex tracks in panels c and d are reminiscent of XTE J1550–564 (Figure 6). The hysteresis in transitions to and from the hard state are especially evident in the HID (panel d; see also Maccarone & Coppi 2003). The overview for XTE J1859+226 (Figure 8), is similar to that of H 1743–322. All of the brightest observations are found in the SPL state, and the vertical track in the HID (green triangles in Figure 8) is a consequence of constant values of in the SPL state. These complex results reinforce the need to probe deeply in attempting to identify the underlying variables that govern the emission of radiation from BHBs.
