------ Start for Possible Stand-alone Circular ----
In response to GRB240101 (Swift/BAT trigger 1205744) at 20:25:39 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 134 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
0.287.

Found 1171 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 22% of the srclist region. Found 190 sources in
srclist catalog. WARNING -- srclist catalog buffer filled. Found 32 srclist

Genie image analysis:
Found 62026.9 counts in the large background region of 5634.0 pixels or a rate
of 11.009 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 19.87 mag. for a
4-arcsec aperture.
Found 2152.9 counts in the XRT position region of 199.0 pixels or a rate of
10.819 counts/pixel in a radius of 8.0 arcsec. The net count rate (using local
background region) at the XRT position is -0.395 +/- 0.336 (1-sigma) cps. The
3-sigma UL at the XRT position is 1.008 cps or 19.60 mag. The number of srclist
sources filled the available telemetry. The weakest source detected was 19.35
mag. The closest srclist source has ra= 352.1076 dec= 51.6389 mag=17.67
