Fig. 5


Comparison of the Sco X-1 like sources with the Cyg X-2like sources. In all figures the Cyg-like sources will be shown as blue filled circles; GX 349+2 will have red open circles and Sco X-1 red filled circles. The nominally Sco-like source GX 17+2 will be shown with green filled squares to emphasize its transitional nature with some characteristics Cyg-like and some Sco-like. To help distinguish between the sub-groups of sources, Sco-like sources have branch labels: H, N and F while Cyg-like sources use h, n and f.
