------ Start for Possible Stand-alone Circular ----
In response to GRB250322 (Swift/BAT trigger 1297832) at 16:06:12 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 76 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 none of
the XRT error circle. 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 0.153.

catalog for Genie image region. The stars will eliminate afterglows from about
22% of the Genie image region.
Genie image analysis:
Found 69122.0 counts in the large background region of 5388.0 pixels or a rate
of 12.829 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 19.79 mag. for a
4-arcsec aperture. The number of srclist sources filled the available
telemetry. The weakest source detected was 19.15 mag. The closest srclist
source has ra= 106.7686 dec= 7.1934 mag=18.88 sep=29.05". The closest Genie
source has ra= 106.7492 dec= 7.1974 mag=17.03 sep=43.20".
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.)
(Magnitudes followed by * have been corrected for exposure.)
