P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team:
There was an error in GCN 13326: the light curve decay slope was
reported as infinity.
The XRT light curve in fact shows a plateau (alpha=0.2 +/-0.4) until
T0+270 seconds. After this it undergoes an extremely sharp decay
(alpha~10) and is not detected in X-rays after T0+1ks.
