Light curves of the 2011 October 15 outburst of IGR J17407−2808 (first Swift orbit data). a) BAT light curve in the 14−50 keV energy band and a binning of 10 s. The horizontal lines mark the time intervals used for the spectral extraction (peak1 and peak2). b) The XRT light curve in the 0.2−10 keV energy band. An adaptive binning has been used to achieve in each point a signal-to-noise ratio of S/N = 3.
