Notes:

¹ Error is 90% confidence, radius

² G=Good, R=Reasonable, P=Poor (What?)

³ AG = Candidate afterglow, I=Interesting source, U=Uncatalogued X-ray source, K=Known X-ray source.

⁴ For uncatalogued sources this is how many sigma above the historical upper limit the source is, for known sources this is how many sigma above the catalogued flux the source is.
