Fig. 2.
X-ray light curve (PN+MOS) of the transient source J1806–27 with a bin time of 30 s. Start time is set at the beginning of the pn observation (MJD = 53634.14811 – all times are in Barycentric Dynamical Time). The inset shows a zoom on the flare. Error bars are computed according to Gehrels (1986). The flare is well described by a Gaussian centered at MJD = 53634.18937 ± 0.00014 and with σ = 54 ± 11 s.
