The burst, also observed by Swift/BAT, had a spectrum well fitted by the sum of two blackbodies with temperatures of ∼4 and 10 keV and a fluence in the 0.3-150 keV energy range of ∼10<SUP>-5</SUP> erg cm<SUP>-2</SUP>. The X-ray tail had a fluence of ∼4 × 10<SUP>-8</SUP> erg cm<SUP>-2</SUP>. Thanks to the knowledge of the distances and relative optical depths of three dust clouds between us and 1E 1547.0-5408, we show that most of the X-rays in the tail can be explained by dust scattering of the burst emission, except for the first ∼20-30 s. We point out that other X-ray tails observed after strong magnetar bursts may contain a non-negligible contribution due to dust scattering.STAMPAenArticle10.1093/mnras/stx3682-s2.0-85052513660000398419400073https://academic.oup.com/mnras/article/467/3/3467/29828822017MNRAS.467.3467PFIS/05 - ASTRONOMIA E ASTROFISICA
