From Cadolle Bel et al. 2009, astro-ph 0903.4714. Unabsorbed spectral energy distribution of \xte\ from radio (VLA at 4.9~GHz) to X-ray/soft $\gamma$-ray data (XRT, PCA, HEXTE and ISGRI from 0.3 up to 200~keV) during the end of Rev. 347/beginning of 348 (i.e., first \integral\ ToO). A strong increase in the VLA flux density was observed in less than 1 day

From Cadolle Bel et al. 2009, astro-ph 0903.4714. Unabsorbed spectral energy distribution of \xte\ including radio (VLA at 1.4, 4.9 and 8.4~GHz), NIR/optical (NTT) and X-ray/soft $\gamma$-ray data (PCA, HEXTE and ISGRI instruments from 3 up to 200~keV) during the second \integral\ ToO (Rev. 349). A simple power law is plotted through the radio data to show the optical excess: at least 3 distinct contributions (jet, disc, hot medium) are needed to fit the data.
