GRB 160910A: Swift observation summary

Source 1 has been manually confirmed as the GRB afterglow; data for this object are now available through the main GRB results area for this GRB.

About tiled field analysis.

So far 6 fields have been scheduled for observations. Data are available and processed for 5 of these. The list gives the exposure time used in source detection. If any individual sources were selected for follow-up observations, the source detection is not repeated for the follow up observations and the table below is not updated.

• 20696 — 1.1 ks of cleaned data taken between 2016-09-11 03:05:44 and 2016-09-11 05:19:46
• 20697 — 1.2 ks of cleaned data taken between 2016-09-11 03:15:13 and 2016-09-11 05:10:37
• 20698 — 1.2 ks of cleaned data taken between 2016-09-11 03:25:22 and 2016-09-11 04:50:27
• 20699 — 1.1 ks of cleaned data taken between 2016-09-11 03:35:34 and 2016-09-11 05:00:37

1 fields were processed but not included in the analysis. This is because, after standard processing and the removal of times contaminated by light reflected off the bright Earth, there was too little data (<100 s) for source detection to be performed.

Probable afterglow details

A source was found which matches the afterglow criteria.
