TITLE: GCN CIRCULAR NUMBER: 18060 SUBJECT: Correction to GCN 18059: Parameterisation of Swift-XRT light curve DATE: 15/07/24 18:39:51 GMT FROM: Kim Page at U.of Leicester K.L. Page, A.P. Beardmore (U. Leicester) and J.L. Racusin (NASA/GSFC) report on behalf of the Swift-XRT team: The description of the XRT light curve given in GCN Circ. 18059 was incorrect. Following significant flaring activity during the first 1.3 ks of data, the light curve from T0+4.7 ks to 24.0 ks remains approximately constant with a mean count rate of 0.04 ct/sec (not 2.2 ct/sec as previously stated). We apologise for any confusion. This circular is an official product of the Swift-XRT team.
