XRT lightcurve of the entire outburst observed by Swift J1734.5-3027 (the start time is set at 56 536.38458 MJD as in Fig. 2 and the bin time is 500 s). The points in cyan represents the long Type-I X-ray burst. The red arrows show the XRT observations in which the source was not detected, providing an upper limit on the source count-rate. The green bands indicate the coverage of the outburst provided by INTEGRAL (data of revolution 1329 are not shown, as they were collected before the Swift discovery). We also indicated with a blue bar the time of the XMM-Newton ToO observation.
