image paragraph message for exposure 1 of trigger 865036
------ Start for Possible Stand-alone Circular ----
In response to GRB181002 (Swift/BAT trigger 865036) at 11:26:43 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 144 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
0.60.

UVOT exposure began at MET 560172569.1774 or about 2018:275:11:29:24 UT
Found 310 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 6% of the srclist region. Found 31 sources in
srclist catalog. Found 0 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 20.55 mag. Found 42 stars in largest star catalog for
Genie image region. The stars will eliminate afterglows from about 6% of the
Genie image region.
Genie image analysis:
Found 76855.4 counts in the large background region of 6318.0 pixels or a rate
of 12.165 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 19.99 mag. for a
4-arcsec aperture.
Found 2390.1 counts in the XRT position region of 199.0 pixels or a rate of
12.011 counts/pixel in a radius of 8.0 arcsec. The net count rate (using local
background region) at the XRT position is -0.227 +/- 0.351 (1-sigma) cps. The
3-sigma UL at the XRT position is 1.054 cps or 19.72 mag. The closest srclist
source has ra= 64.7357 dec= 15.2131 mag=16.29 sep=37.78". The closest Genie
source has ra= 64.7357 dec= 15.2130 mag=15.61 sep=38.05".
All AG candidates sorted by magnitude for the current finding chart.
(U/V/White SRCLIST mags < 17.5/17.5/18.5 are reliable. Mag > 18.5/18.5/19.5 are
not. Others are uncertain.)
(U/V/White Genie image mags < 18.0/18.0/19.0 are reliable. Mag > 19.0/19.0/20.0
are not. Others are uncertain.)
