srclist paragraph message for exposure 1 of trigger 846299
IMAGE PROBLEM: no overlap
------ Start for Possible Stand-alone Circular ----
In response to GRB180705 (Swift/BAT trigger 846299) at 15:41:14 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 117 seconds with the White filter
starting 3366 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 0.06.
