There were complications with the spacecraft attitude which affected this GRB. Although the automatic software has been patched and the attitude file rebuilt, everything is still under testing, and there may be further changes to this light curve.
Non-standard pipeline processing was used to produce these data. The pointing accuracy requirements for the first snapshot has been removed, and the UVOT-derived attitude file used.
For this burst, 1 count = 4.01 x 10-11 erg cm-2 (observed flux) (Automatic spectrum).
Note that this is an average conversion factor: the true value may evolve with time.
