GX 339-4 X-ray light curve in the 3–200 keV energy band of the 2000–2010 decade obtained with the Clavel et al. (2016) fits. The violet filled region shows the power law unabsorbed flux, while the cyan region represents the disk unabsorbed flux. The selected spectra for this study are highlighted in gray: the rising and decaying hard states of the four outbursts (1, 2, 3, and 4). At the top the red lines represent the date when steady radio fluxes were observed at 9 GHz (from Corbel et al. 2013).
