srclist paragraph message for exposure 1 of trigger 1413695
IMAGE PROBLEM: no overlap
------ Start for Possible Stand-alone Circular ----
In response to GRB251112 (Swift/BAT trigger 1413695) at 21:28:55 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 91 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 none of the XRT error circle. No correction has been made for
the expected extinction corresponding to E(B-V) of 0.158.

Found 890 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 17% of the srclist region. Found 136 sources in
srclist catalog. Found 12 srclist source(s) without IDs. There are 0 good
candidate(s) in the srclist catalog. Good candidates must be brighter than

search region.
Genie image analysis:
Found 109885.1 counts in the large background region of 5716.0 pixels or a rate
of 19.224 counts/pixel in a radius of 45.0 arcsec. Based on this background,
the typical 5-sigma UL at a random point in the Genie image is 19.57 mag. for a
4-arcsec aperture. The closest srclist source has ra= 274.0677 dec= 24.1692
