Rate in xrt_bkg region from 15 to 25 arcsec is 18.260 counts/pixel (5-sig UL in 4" is 19.77 mag) for 1217729_g186
There are 3 candidate(s) outside XRT error circle with mag < 19.78
Good candidates have no ID, acceptable profiles,
mag between 9.01 and 20.34, XRT distances < 11.75",
are > ~(80 - 10*(mag-6))" from any bright star, and have had duplicates removed.
SUMMARY: 0 good candidate(s) found.
Results are questionable because aspect solution FAILED.

image paragraph message for exposure 1 of trigger 1217729
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.
6 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 GRB240227 (Swift/BAT trigger 1217729) at 04:46:47 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 154 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 0.347.

XRT position found for Genie image. BAT position found.
UVOT exposure began at MET 730702194.7448 or about 2024:058:04:49:49 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 34 source(s) in Genie image catalog. 6 source(s) are within 20.0" of the
xrt position. Found 34 Genie image source(s) without IDs. There are 0 good
candidate(s) in the Genie image catalog. Good candidates must be brighter than
20.34 mag. Found 142 stars in largest star catalog for Genie image region. The
stars will eliminate afterglows from about 14% of the Genie image region.
Found 6 Genie source(s) within 20.0" of the XRT position. The brightest such
source has ra= 245.3496 dec= -15.6597 mag=18.55 sep=5.27". The closest Genie
source has ra= 245.3496 dec= -15.6597 mag=18.55 sep=5.27".
This paragraph is only useful if the XRT position is grossly wrong. There are 3
candidate(s) in the image data with mag < 19.78 inside the BAT error region,
but outside the XRT error region. The brightest such source is at RA=245.37462
(16:21:29.91), DEC=-15.66125 (-15:39:40.5) (J2000). It has a mag of 18.27. It
is 156.9" 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 154 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 16:21:29.91 = 245.37462
DEC(J2000) = -15:39:40.5 = -15.66125
with a 90%-confidence error radius of about 0.76 arc sec. The estimated
magnitude is 18.27 with a 1-sigma error of about 0.15. No correction has been
made for the expected extinction corresponding to E(B-V) of 0.347.
Report rejected UVOT sources within 10 arcsec XRT position.
Such sources are usually NOT the afterglow.
****THIS SOURCE NEAR XRT POSITION WAS REJECTED--USE WITH CAUTION****
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 154 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 16:21:23.91 = 245.34964
DEC(J2000) = -15:39:34.8 = -15.65966
with a 90%-confidence error radius of about 0.76 arc sec. This position is 5.27
arc sec. from the center of the XRT error circle. The estimated magnitude is
18.55 with a 1-sigma error of about 0.15. No correction has been made for the
expected extinction corresponding to E(B-V) of 0.347.
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.)
