------ Start for Possible Stand-alone Circular ----
In response to GRB181126 (Swift/BAT trigger 873539) at 09:54:08 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 868 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
0.07.

Genie image analysis:
Found 222490.6 counts in the large background region of 5909.0 pixels or a rate
of 37.653 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 19.38 mag. for a
4-arcsec aperture.
Found 7896.5 counts in the XRT position region of 199.0 pixels or a rate of

This paragraph is only useful if the XRT position is grossly wrong. There are 6
candidate(s) in the srclist data with mag < 18.66 inside the BAT error region,
but outside the XRT error region. The brightest such source is at RA=152.36126
