srclist paragraph message for exposure 1 of trigger 1180410
------ Start for Possible Stand-alone Circular ----
In response to GRB230723 (Swift/BAT trigger 1180410) at 11:42:32 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 3298 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
100% of the XRT error circle. The typical 3-sigma upper limit has been about
19.6 mag. 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 0.411.

Found 506 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 11% of the srclist region. Found 38 sources in
srclist catalog. Found 6 srclist source(s) without IDs. There are 0 good
candidate(s) in the srclist catalog. Good candidates must be brighter than
19.22 mag.
Found 6 source(s) in Genie image catalog. Found 0 Genie image source(s) without
IDs. There are 0 good candidate(s) in the Genie image catalog. Good candidates
must be brighter than 20.19 mag. Found 100 stars in largest star catalog for

Genie image analysis:
Found 142325.3 counts in the large background region of 6083.0 pixels or a rate
of 23.397 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 19.46 mag. for a
4-arcsec aperture.
Found 4701.3 counts in the XRT position region of 198.0 pixels or a rate of
23.744 counts/pixel in a radius of 8.0 arcsec. The net count rate (using local
background region) at the XRT position is 0.043 +/- 0.498 (1-sigma) cps or
23.02 mag and a range from 20.27 to 99.99 mag. The 3-sigma UL at the XRT
position is 1.537 cps or 19.14 mag. The closest srclist source has ra= 250.3772
dec= -5.3383 mag=16.57 sep=13.57". The closest Genie source has ra= 250.3772
