About tiled field analysis.

Swift is observing this GRB in a series of observations which are tiled on the sky.
So far 2 fields have been scheduled for observations.
Data are available and processed for 2 of these.

The source details on this page are for the observing campaign as a whole. For any object which is detected in multiple fields, the fluxes given here are the average across all fields. The position is the best position from all fields, and the peak flux is likewise determined. If you go the results page for a specific field (indexed by target ID) the values shown there are specific to the data for that field.


Sources found so far

So far 1 sources have been found in the XRT data, with a further 3 subthreshold sources found. In total 1 possible sources match catalogued sources.

A catalogued source matches this source's position.

1Radius, 90% confidence.

2Bayesian probability that the source is a background fluctuation. Note that this is strongly dependent on the estimated background and may be an underestimate. Values >0.3% mean the source is subthreshold according to the Bayesian approach, i.e. less than 3-σ significance.Otherwise sources listed as subthreshold in the notes column are those which were not detected by the celldetect, with a frequentist SNR limit of 3.
