srclist paragraph message for exposure 3 of trigger 1032183
IMAGE PROBLEM: no overlap
------ Start for Possible Stand-alone Circular ----
In response to GRB210212 (Swift/BAT trigger 1032183) at 04:25:18 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 56 seconds with the White filter
starting 873 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 mag. No correction has been made for the expected
extinction corresponding to E(B-V) of 0.094.
