image paragraph message for exposure 1 of trigger 1209370
THIS MESSAGE IS *NOT* READY FOR DISTRIBUTION.
MORE ANALYSIS IS REQUIRED TO DETERMINE WHETHER THERE IS AN AFTERGLOW CANDIDATE.
IMAGE PROBLEM: no aspect solution

------ Start for Possible Stand-alone Circular ----
In response to GRB240117 (Swift/BAT trigger 1209370) at 07:48:31 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 0.401.

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 25 source(s) in Genie image catalog. 1 source(s) are within 20.0" of the
xrt position. Found 25 Genie image source(s) without IDs. There are 0 good
candidate(s) in the Genie image catalog. Good candidates must be brighter than
19.99 mag. Found 107 stars in largest star catalog for Genie image region. The
stars will eliminate afterglows from about 13% of the Genie image region.
Found 1 Genie source(s) within 20.0" of the XRT position. The brightest such
source has ra= 245.5733 dec= -15.9132 mag=17.47 sep=11.36". The closest Genie
source has ra= 245.5733 dec= -15.9132 mag=17.47 sep=11.36".
This paragraph is only useful if the XRT position is grossly wrong. There are 4
candidate(s) in the image data with mag < 19.43 inside the BAT error region,
but outside the XRT error region. The brightest such source is at RA=245.57974
(16:22:19.14), DEC=-15.91113 (-15:54:40.1) (J2000). It has a mag of 17.97. It
is 162.6" 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) = 16:22:19.14 = 245.57974
DEC(J2000) = -15:54:40.1 = -15.91113
with a 90%-confidence error radius of about 0.76 arc sec. The estimated
magnitude is 17.97 with a 1-sigma error of about 0.15. No correction has been
made for the expected extinction corresponding to E(B-V) of 0.401.
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.)
