Source 2 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 3 fields have been scheduled for observations. Data are available and processed for 4 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.

21670 — 1.2 ks of cleaned data taken between 2024-02-16 03:50:59 and 2024-02-16 04:14:40
21671 — 1.3 ks of cleaned data taken between 2024-02-16 05:25:58 and 2024-02-16 05:50:24
21672 — 1.3 ks of cleaned data taken between 2024-02-16 07:00:51 and 2024-02-16 07:24:21
21673 — 661 s of cleaned data taken between 2024-02-16 07:24:24 and 2024-02-16 08:50:52

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.
