GRB 170306B: Swift observation summary

About tiled field analysis.

So far 7 fields have been scheduled for observations. Data are available and processed for 7 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.

• 20745 — 626 s of cleaned data taken between 2017-03-06 18:56:57 and 2017-03-06 22:19:26
• 20746 — 654 s of cleaned data taken between 2017-03-06 19:03:02 and 2017-03-06 22:21:36
• 20747 — 656 s of cleaned data taken between 2017-03-06 19:09:03 and 2017-03-06 22:24:38
• 20748 — 664 s of cleaned data taken between 2017-03-06 19:15:03 and 2017-03-06 22:23:47
• 20749 — 644 s of cleaned data taken between 2017-03-06 19:21:02 and 2017-03-06 22:20:21
• 20750 — 651 s of cleaned data taken between 2017-03-06 19:27:04 and 2017-03-06 22:22:28
• 20751 — 621 s of cleaned data taken between 2017-03-06 19:32:52 and 2017-03-06 22:17:47

An additional 1 field has also been used for follow up observations. These data are not searched for sources, but are used to update the light curves etc of any sources already found.

¹ Radius, 90% confidence.
² Indicates how likely the source is to be real. See the 1SXPS documentation.
^* The position was enhanced using astrometry derived from the Swift UVOT.
^† The position was astrometrically corrected using the XRT sources and the 2MASS catalogue.
