From Cadolle Bel et al 2007 ApJ, 659, 549. Simultaneous observations in the Low/Hard State. Their Figure 10: Spectral energy distribution of SwJ1753.5-0127on August 11 with radio (15~GHz upper limit data point excluded), IR, optical and X-ray points (up to 535~keV) and errors. The NIR and optical flux densities (filters B, V, R, I, J, H and K) were dereddened with A_V=~1.05$\pm$0.12 mag (see text). A simple power law can not fit all the points together: there are at least three disctinct contributions (the optically thick synchrotron emission from the jet, the thermal disk and Comptonization of soft photons by a hot medium)
