Fig. 2.
XMM-Newton PN background-corrected light curves of observation 0556140801 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-to-hard color ratio. Blue stripes correspond to two flaring intervals where the rate significantly increases in both soft and hard bands, keeping an average color value consistent with the rest of the observation. Error bars correspond to the 1-σ confidence level.
