Examples of our XDF flags that label the 3PBC sources. Each panel shows an image from XRT-merged event files, with the red circle indicating the BAT positional uncertainty region and the black circles highlighting the position of a soft X-ray source detected in the Swift-XRT archive. The left panel is an example of a 3PBC source with a single Swift-XRT source found within the BAT positional uncertainty region (red circle), flag x. The center panel is a case of multiple detected Swift-XRT counterparts inside the BAT positional uncertainty, flag m. The right panel is an example of no Swift-XRT counterparts detected within the BAT positional uncertainty region, flag u.
