The image below shows the UVOT field with the final, astrometrically corrected XRT refined position. The image is 50" to a side, and contains 2e+03 s of data in the B filter.
The final position (magenta) is the weighted mean of 7 positions (green). A further 1 positions were rejected, either because they had too few photons to be secure (red) or because they are more than 3 sigma away from the mean position, more than 40" from the early mean, or had a problematic astrometric correction (yellow). The image is 50" to a side.
