Methods and results of an automatic analysis of a complete sample of Swift-XRT observations of GRBs
The rapid real-time determination of accurate GRB positions plays a key role in GRB follow-up and is essential for host-galaxy identification. XRT positions are determined from knowledge of the spacecraft attitude and a precise mapping between the UVOT and XRT detectors. At the time of writing there was genuine concern that the accuracy of XRT positions was declining, possibly as a result of flexure in the optical bench. Following on from my original work (Goad et al. 2007) I was able to verify that the mapping between the UVOT and XRT detectors was unchanged, and that published positions were valid.
