srclist paragraph message for exposure 1 of trigger 1274039
IMAGE PROBLEM: no overlap
------ Start for Possible Stand-alone Circular ----
In response to GRB241213 (Swift/BAT trigger 1274039) at 02:19:00 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 250 seconds with the U filter starting
318 seconds after the BAT trigger. No credible afterglow candidate has been
found in the initial data products. The 2.7'x2.7' sub-image covers none of the
XRT error circle. The 8'x8' region for the list of sources generated on-board
covers 100% of the XRT error circle. The list of sources is typically complete
to about 18.0 mag. No correction has been made for the expected extinction
corresponding to E(B-V) of 0.060.
