image paragraph message for exposure 1 of trigger 1191903
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.
------ Start for Possible Stand-alone Circular ----
In response to GRB230913 (Swift/BAT trigger 1191903) at 16:44:15 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 186 seconds with the U filter starting
123 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 716316411.70806 or about 2023:256:16:46:46 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 11 source(s) in Genie image catalog. Found 11 Genie image source(s)
without IDs. There are 0 good candidate(s) in the Genie image catalog. Good
candidates must be brighter than 19.91 mag. Found 248 stars in largest star
catalog for Genie image region. The stars will eliminate afterglows from about
43% of the Genie image region. The Genie image is INCOMPLETE with 12287 null
pixels.
The closest Genie source has ra= 299.6482 dec= 35.4121 mag=14.84 sep=20.98".
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.)
