image paragraph message for exposure 1 of trigger 1220091
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

------ Start for Possible Stand-alone Circular ----
In response to GRB240314 (Swift/BAT trigger 1220091) at 22:35:26 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 102 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 0.216.

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 21 source(s) in Genie image catalog. Found 21 Genie image source(s)
without IDs. There are 0 good candidate(s) in the Genie image catalog. Good
candidates must be brighter than 20.30 mag. Found 130 stars in largest star
catalog for Genie image region. The stars will eliminate afterglows from about
17% of the Genie image region. The closest Genie source has ra= 243.7447 dec=
-15.3931 mag=19.61 sep=29.46".
This paragraph is only useful if the XRT position is grossly wrong. There are 1
candidate(s) in the image data with mag < 19.74 inside the BAT error region,
but outside the XRT error region. The brightest such source is at RA=243.75149
(16:15:00.36), DEC=-15.39425 (-15:23:39.3) (J2000). It has a mag of 18.22. It
is 164.9" from the BAT position.
****THIS SOURCE IS OUTSIDE XRT ERROR CIRCLE--USE WITH CAUTION***
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 102 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 16:15:00.36 = 243.75149
DEC(J2000) = -15:23:39.3 = -15.39425
with a 90%-confidence error radius of about 0.76 arc sec. The estimated
magnitude is 18.22 with a 1-sigma error of about 0.15. No correction has been
made for the expected extinction corresponding to E(B-V) of 0.216.
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
