Source 3 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 2 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.
