Infrared-to-X-ray spectral energy distribution for 1E 1207.4−5209. Flux limits from HST and VLT data – corrected for interstellar reddening assuming N_H = 1.3  ×  10²¹ cm^-2 and using the relations by Predehl & Schmitt (1995) and Cardelli et al. (1989) – are shown, together with the limits from Spitzer data given by Wang et al. (2007). The expected flux from a fallback disk, assuming i = 60°, B = 8  ×  10¹⁰ G, ṁ = 8  ×  10¹¹ g s^-1 and r_out = 2  ×  10¹² cm (see text), consistent with the upper limits, is plotted as a red dashed line. The X-ray spectrum as observed by XMM-Newton (De Luca et al. 2004) is also plotted as a solid black line.
