List UVOT sources within 10" of the XRT position:
There are no candidates inside BAT error circle, but outside XRT error circle.
Good candidates have no ID, acceptable profiles,
mag between 9.01 and 19.22, XRT distances < 5",
are > ~(80 - 10*(mag-6))" from any bright star, and have had duplicates removed.
SUMMARY: 0 good candidate(s) found.
srclist paragraph message for exposure 1 of trigger 1348587
THIS MESSAGE IS *NOT* READY FOR DISTRIBUTION.
MORE ANALYSIS IS REQUIRED TO DETERMINE WHETHER THERE IS AN AFTERGLOW CANDIDATE.
IMAGE PROBLEM: high density of stars
SRCLIST PROBLEM: high density of stars, srclist filled telemetry buffer
See notes for more details.
------ Start for Possible Stand-alone Circular ----
In response to GRB250911 (Swift/BAT trigger 1348587) at 01:27:46 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 3445 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. Because of the density of catalogued stars,
further analysis is required to report an upper limit for any afterglow in the
sub-image. The 8'x8' region for the list of sources generated on-board covers
100% of the XRT error circle. Because of the density of catalogued stars,
further analysis is required to report an upper limit for any afterglow in the
region. No correction has been made for the expected extinction corresponding
to E(B-V) of 0.486.

Since the srclist star catalog filled its buffer, the sensitivity for an
afterglow may be REDUCED. The stars will eliminate afterglows from about 93%
or more of the srclist region. Found 190 sources in srclist catalog. WARNING --
srclist catalog buffer filled. Found 17 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 51 source(s) in Genie image catalog. Found 1 Genie image source(s)
without IDs. There are 0 good candidate(s) in the Genie image catalog. Good
candidates must be brighter than 20.06 mag. Found 1463 stars in largest star
catalog for Genie image region. The stars will eliminate afterglows from about
148% of the Genie image region.
Genie image analysis:
Found 163256.2 counts in the large background region of 5474.0 pixels or a rate
of 29.824 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 19.33 mag. for a
4-arcsec aperture.
Found 5897.6 counts in the XRT position region of 198.0 pixels or a rate of
29.786 counts/pixel in a radius of 8.0 arcsec. The net count rate (using local
background region) at the XRT position is 1.460 +/- 0.566 (1-sigma) cps or
19.19 mag and a range from 18.84 to 19.73 mag. The 3-sigma UL at the XRT
position is 3.158 cps or 18.36 mag. The number of srclist sources filled the
available telemetry. The weakest source detected was 18.44 mag. The closest
srclist source has ra= 263.7518 dec= -16.8581 mag=16.36 sep=15.25". The closest
