Fig. 3.
XMM-Newton PN background-corrected light curves of observation 0556140101 of IGR J16320–4751 using 20 s binning time. Top panel: soft band (0.5–6.0 keV) rate in cts s−1. Central panel: hard band (6.0–12.0 keV) rate in cts s−1. Bottom panel: soft/hard color ratio. The blue lines indicate a significant variation in the source state at ∼7000 s both in the count-rates and in the color ratio. Error bars correspond to 1-σ confidence level.
