Top: broadband best-fit (solid lines) to the HUL states of Holmberg II X–1 (orange) and NGC 5204 X–1 (purple line) with the self-irradiated super-critical funnel model (sirf in XSPEC) for i ∼ 10° (see Table 6). The models in the upper panel have been corrected for X-ray and optical absorption. Lower panels: best-fit residuals for Holmberg II X–1 (middle panel) and NGC 5204 X–1 (bottom panel) without any correction for X-ray absorption. Green, red, and blue circles show the HST, XMM-Newton EPIC-pn, and FPMA NuSTAR data, respectively (see Table 6).
