GRB 250206A: Swift observation summary

About tiled field analysis.

So far 10 fields have been scheduled for observations. Data are available and processed for 10 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.
