image paragraph message for exposure 2 of trigger 1219994
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.
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 GRB240314 (Swift/BAT trigger 1219994) at 00:11:50 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 250 seconds with the U filter starting
312 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 0.254.

XRT position found for Genie image. BAT position found.
UVOT exposure began at MET 732068256.31158 or about 2024:074:00:17:31 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. 2 source(s) are within 20.0" of the
xrt position. 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
20.21 mag. Found 136 stars in largest star catalog for Genie image region. The
stars will eliminate afterglows from about 13% of the Genie image region.
Found 2 Genie source(s) within 20.0" of the XRT position. The brightest such
source has ra= 244.7511 dec= -16.1950 mag=16.52 sep=15.71". The closest Genie
source has ra= 244.7511 dec= -16.1950 mag=16.52 sep=15.71".
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.)
