image paragraph message for exposure 1 of trigger 1217733
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.
------ Start for Possible Stand-alone Circular ----
In response to GRB240227 (Swift/BAT trigger 1217733) at 05:40:31 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 182 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 expected extinction corresponding to E(B-V) of 0.647.

No XRT position found for Genie image. BAT position found.
UVOT exposure began at MET 730705446.70826 or about 2024:058:05:44:01 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 13 source(s) in Genie image catalog. Found 13 Genie image source(s)
without IDs. There are 0 good candidate(s) in the Genie image catalog. Good
candidates must be brighter than 19.82 mag. Found 165 stars in largest star
catalog for Genie image region. The stars will eliminate afterglows from about
18% of the Genie image region.
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.)
(Magnitudes followed by * have been corrected for exposure.)
