Qualitative evolution of the fluorescence signal from the CND (blue) due to the outburst of the magnetar SGR J1745–2900. The region from which a Fe Ka signal is expected is highlighted in orange. The density of the torus structure is assumed to be constant and uniform. We assume that the outburst had a one-year duration. The magnetar is assumed to be in the position (x, y, z) = (0.1, −0.1,0.0) pc. A different position along the LOS translates in different time delays. An animated version is available onlne.
