image paragraph message for exposure 2 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 865 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.
Data from the list of sources generated on-board are not available at this
time. No correction has been made for the expected extinction corresponding to
E(B-V) of 0.008.

UVOT exposure began at MET 678344872.68232 or about 2022:182:05:07:47 UT
No information found about the number of stars in the star catalog for srclist
region.
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 21.06 mag. Found 104 stars in largest star
catalog for Genie image region. The stars will eliminate afterglows from about
10% of the Genie image region.
Genie image analysis:
Found 28256.3 counts in the large background region of 5958.0 pixels or a rate
of 4.743 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 20.33 mag. for a
4-arcsec aperture.
Found 889.6 counts in the XRT position region of 196.0 pixels or a rate of
4.539 counts/pixel in a radius of 8.0 arcsec. The net count rate (using large
background region) at the XRT position is -0.266 +/- 0.202 (1-sigma) cps. The
3-sigma UL at the XRT position is 0.607 cps or 20.15 mag. The closest Genie
source has ra= 242.4944 dec= 55.4139 mag=19.27 sep=29.90".
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.)
