Top: Characteristic frequencies ν_LF and ν_LF/2 (see text) vs. ﹩\nu _{h}﹩. The symbols are labeled in the plot and represent the frequencies of the QPOs in the atoll sources 4U 1728−34, 4U 0614+09, 4U 1608−52, and 4U 1820−30; the BHCs Cyg X‐1 and GX 339−4; the low‐luminosity bursters 1E 1724−3045 and GS 1826−24, and the AMPs XTE J0929−314, XTE J1814−338, and SAX J1808.4−3658 (van Straaten et al. 2003, 2005; Altamirano et al. 2005). The filled triangles show the results for 4U 1636−53. The solid line indicates a power‐law fit to the ν_LF vs. ﹩\nu _{h}﹩ relation of the low‐luminosity bursters 1E 1724−3045 and GS 1826−24 and the BHC GX 339−4. The dashed line shows a power law with a normalization half that of the solid line. Bottom: Zoom of the high‐frequency region.
