srclist paragraph message for exposure 1 of trigger 1310284
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

------ Start for Possible Stand-alone Circular ----
In response to GRB250504 (Swift/BAT trigger 1310284) at 23:25:57 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 250 seconds with the U filter starting
137 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 0.00% of the XRT
error circle. No correction has been made for the expected extinction
corresponding to E(B-V) of 0.191.

Genie image analysis:
Found 27456.5 counts in the large background region of 4486.0 pixels or a rate
of 6.120 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 19.28 mag. for a
4-arcsec aperture.
Found 1274.7 counts in the XRT position region of 203.0 pixels or a rate of
6.279 counts/pixel in a radius of 8.0 arcsec. The net count rate (using large
background region) at the XRT position is 0.129 +/- 0.146 (1-sigma) cps or
20.36 mag and a range from 19.54 to 99.99 mag. The 3-sigma UL at the XRT
position is 0.567 cps or 18.75 mag. The number of srclist sources filled the
