RXTE ASM and PCA light curves for V4641 Sgr together with H.E.S.S. upper limits derived from individual ~ 28 min runs using standard event selection cuts. The blue shaded bands on the ASM light curve indicate the extent of the H.E.S.S. observations, while on the H.E.S.S. upper limit plots they illustrate the duration of the contemporaneous PCA observations. The plotted H.E.S.S. upper limits correspond to different threshold energies and the vertical scale of eachlight curve has been optimised for the plotted data.
