Modelling the spectral response of the <i>Swift</i>-XRT CCD camera: experience learnt from in-flight calibration
<i>Context. <i/>Since its launch in November 2004, <i>Swift<i/> has revolutionised our understanding of gamma-ray bursts. The X-ray telescope (XRT), one of the three instruments on board <i>Swift<i/>, has played a key role in providing essential positions, timing, and spectroscopy of more than 300 GRB afterglows to date. Although <i>Swift<i/> was …
