There are 26836.273 counts in the bkg source region of 5296.0000 pixels.
Rate in bkg region from 0 to 45 arcsec is 5.067 counts/pixel (5-sig UL in 4" is 19.58 mag) for 1192485_g209
There are 1142.5327 counts in the xrt source region of 198.00000 pixels.
Rate in xrt region with 8 arcsec radius is 5.770 counts/pixel for 1192485_g209
There are 4564.8472 counts in the xrt_bkg source region of 915.00000 pixels.
Rate in xrt_bkg region from 15 to 25 arcsec is 4.989 counts/pixel (5-sig UL in 4" is 19.59 mag) for 1192485_g209
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 20.14, XRT distances < 15",
are > ~(80 - 10*(mag-6))" from any bright star, and have had duplicates removed.
SUMMARY: 0 good candidate(s) found.
Results are questionable because aspect solution FAILED.

image paragraph message for exposure 1 of trigger 1192485
THIS MESSAGE IS *NOT* READY FOR DISTRIBUTION.
MORE ANALYSIS IS REQUIRED TO DETERMINE WHETHER THERE IS AN AFTERGLOW CANDIDATE.
IMAGE PROBLEM: no aspect solution
SRCLIST PROBLEM: no srclist afterglow info
See notes for more details.
WARNING -- because of the LARGE EXTINCTION, results should be used cautiously.
2 source(s) near the XRT position were rejected as afterglow candidate(s). See
notes for details.
------ Start for Possible Stand-alone Circular ----
In response to GRB230918 (Swift/BAT trigger 1192485) at 02:52:55 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 250 seconds with the U filter starting
177 seconds after the BAT trigger. No credible afterglow candidate has been
found in the initial data products. The 2.7'x2.7' sub-image processing FAILED
because of no aspect solution. Results from the list of sources generated
on-board are not available at this time. No correction has been made for the
large, but uncertain, extinction expected.

UVOT exposure began at MET 716698585.9115 or about 2023:261:02:56:20 UT
No information found about the number of stars in the star catalog for srclist
region.
THERE IS NO ASPECT SOLUTION for the image data.
Found 17 source(s) in Genie image catalog. 2 source(s) are within 20.0" of the
xrt position. Found 17 Genie image source(s) without IDs. There are 0 good
candidate(s) in the Genie image catalog. Good candidates must be brighter than
20.14 mag. Found 283 stars in largest star catalog for Genie image region. The
stars will eliminate afterglows from about 42% of the Genie image region. The
Genie image is INCOMPLETE with 5045 null pixels.
Found 2 Genie source(s) within 20.0" of the XRT position. The brightest such
source has ra= 299.6179 dec= 35.4699 mag=16.75 sep=15.60". The closest Genie
source has ra= 299.6179 dec= 35.4699 mag=16.75 sep=15.60".
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.)
