srclist paragraph message for exposure 3 of trigger 1152764
------ Start for Possible Stand-alone Circular ----
In response to GRB230205 (Swift/BAT trigger 1152764) at 10:29:51 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of nominal 150.000 seconds with the White
filter starting 859 seconds after the BAT trigger. No credible afterglow
candidate has been found in the initial data products. Data from the 2.7'x2.7'
sub-image are not available at this time. 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 0.036.
