There are no candidates inside BAT error circle, but outside XRT error circle.
Good candidates have no ID, acceptable profiles,
mag between 9.01 and 19.22, XRT distances < 5.5",
are > ~(80 - 10*(mag-6))" from any bright star, and have had duplicates removed.
SUMMARY: 1 good candidate(s) found.
srclist paragraph message for exposure 1 of trigger 1231488
WARNING -- because of the LARGE EXTINCTION, results should be used cautiously.
1 source(s) near the XRT position were rejected as afterglow candidate(s). See
notes for details.
------ Start for Possible Stand-alone Circular ----
In response to GRB240529 (Swift/BAT trigger 1231488) at 02:58:30 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 128 seconds after the BAT trigger. There is a candidate afterglow in
the list of sources generated on-board at
RA(J2000) = 22:21:26.04 = 335.35851
DEC(J2000) = +51:33:43.4 = 51.56205
with a 90%-confidence error radius of about 1.10 arc sec. This position is 2.8
arc sec. from the center of the XRT error circle. The estimated magnitude is
17.84. No correction has been made for the large, but uncertain, extinction
expected.
