List UVOT sources within 10" of the XRT position:
There are no candidates inside BAT error circle, but outside XRT error circle.
Good candidates have no ID, acceptable profiles,
mag between 9.01 and 19.22, XRT distances < 5",
are > ~(80 - 10*(mag-6))" from any bright star, and have had duplicates removed.
SUMMARY: 0 good candidate(s) found.
srclist paragraph message for exposure 1 of trigger 824063
WARNING -- because of the LARGE EXTINCTION, results should be used cautiously.
2 source(s) near the XRT position were rejected as afterglow candidate(s). See
notes for details.
------ Start for Possible Stand-alone Circular ----
In response to GRB180410 (Swift/BAT trigger 824063) at 08:02:59 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 179 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 large, but uncertain, extinction expected.

Genie image analysis:
Found 118318.7 counts in the large background region of 5549.0 pixels or a rate
of 21.323 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 19.69 mag. for a
4-arcsec aperture.
Found 4534.6 counts in the XRT position region of 200.0 pixels or a rate of
22.673 counts/pixel in a radius of 8.0 arcsec. The net count rate (using local
background region) at the XRT position is 1.530 +/- 0.489 (1-sigma) cps or
19.32 mag and a range from 19.02 to 19.74 mag. The 3-sigma UL at the XRT
position is 2.996 cps or 18.59 mag. The closest srclist source has ra= 95.9602

Found 2 Genie source(s) within 10.0" of the XRT position. The brightest such
source has ra= 95.9573 dec= 12.8103 mag=19.53 sep=4.14". The closest Genie
