srclist paragraph message for exposure 1 of trigger 1114034
------ Start for Possible Stand-alone Circular ----
In response to GRB220701 (Swift/BAT trigger 1114034) at 04:52:58 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 175 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
0.008.

Found 486 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 10% of the srclist region. Found 48 sources in
srclist catalog. Found 7 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 11 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 21.05 mag. Found 104 stars in largest star

9% of the Genie image region.
Genie image analysis:
Found 28891.0 counts in the large background region of 5959.0 pixels or a rate
of 4.848 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 20.32 mag. for a
4-arcsec aperture.
Found 950.8 counts in the XRT position region of 199.0 pixels or a rate of
4.778 counts/pixel in a radius of 8.0 arcsec. The net count rate (using large
background region) at the XRT position is -0.093 +/- 0.209 (1-sigma) cps. The
3-sigma UL at the XRT position is 0.627 cps or 20.11 mag. The closest srclist
source has ra= 242.4937 dec= 55.4153 mag=20.90 sep=34.47". The closest Genie
source has ra= 242.4939 dec= 55.4140 mag=19.04 sep=30.87".
