Hardness-intensity diagram of GRS 1915+105 derived from the entire archival RXTE PCA data set. The temporal sampling is 16 s. Hardness is defined as the ratio of fluxes measured in the 2−9 keV and 9−20 keV bands, while intensity is defined as the sum of the band-limited fluxes in units of counts per second. Data corresponding to H.E.S.S. observations are highlighted using symbols to identify the individual days of observation. For comparison, the data corresponding to noteworthy events such as known flares observed by RXTE are also plotted (see e.g. Soleri et al. 2006).
