There are no candidates inside BAT error circle, but outside XRT error circle.
Good candidates have no ID, acceptable profiles,
mag between 9.01 and 19.22, XRT distances < 12",
are > ~(80 - 10*(mag-6))" from any bright star, and have had duplicates removed.
SUMMARY: 0 good candidate(s) found.
srclist paragraph message for exposure 1 of trigger 1220736
THIS MESSAGE IS *NOT* READY FOR DISTRIBUTION.
MORE ANALYSIS IS REQUIRED TO DETERMINE WHETHER THERE IS AN AFTERGLOW CANDIDATE.
IMAGE PROBLEM: high density of stars
SRCLIST PROBLEM: high density of stars, srclist filled telemetry buffer
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 GRB240408 (Swift/BAT trigger 1220736) at 15:13:54 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 141 seconds after the BAT trigger. No credible afterglow candidate has
been found in the initial data products. The 2.7'x2.7' sub-image covers 100% of
the XRT error circle. Because of the density of catalogued stars, further
analysis is required to report an upper limit for any afterglow in the
sub-image. The 8'x8' region for the list of sources generated on-board covers
100% of the XRT error circle. Because of the density of catalogued stars,
further analysis is required to report an upper limit for any afterglow in the
region. No correction has been made for the expected extinction corresponding
to E(B-V) of 0.287.

XRT position found for srclist. XRT position found for Genie image. BAT
position found.
UVOT exposure began at MET 734282209.11458 or about 2024:099:15:16:44 UT
Found 5000 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 110% of the srclist region. Found 190 sources
in srclist catalog. WARNING -- srclist catalog buffer filled. Found 17 srclist
source(s) without IDs. There are 0 good candidate(s) in the srclist catalog.
Good candidates must be brighter than 19.22 mag.
Found 64 source(s) in Genie image catalog. 2 source(s) are within 10.0" 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
20.46 mag. Found 1358 stars in largest star catalog for Genie image region. The
stars will eliminate afterglows from about 123% of the Genie image region.
Genie image analysis:
Found 62335.5 counts in the large background region of 4365.0 pixels or a rate
of 14.281 counts/pixel in a radius of 45.0 arcsec. Based on this background,
the typical 5-sigma UL at a random point in the Genie image is 19.73 mag. for a
4-arcsec aperture.
Found 7230.0 counts in the XRT position region of 198.0 pixels or a rate of
36.515 counts/pixel in a radius of 8.0 arcsec. The net count rate (using local
background region) at the XRT position is 29.539 +/- 0.588 (1-sigma) cps or
15.93 mag and a range from 15.91 to 15.95 mag. The 3-sigma UL at the XRT
position is 31.303 cps or 15.87 mag. The number of srclist sources filled the
available telemetry. The weakest source detected was 18.83 mag.
Found 2 srclist source(s) within 10.0" of the XRT position.
The brightest such source has ra= 236.9765 dec= -62.5657 mag=18.20 sep=0.93".
The closest srclist source has ra= 236.9765 dec= -62.5657 mag=18.20 sep=0.93".
Found 2 Genie source(s) within 10.0" of the XRT position. The brightest such
source has ra= 236.9757 dec= -62.5655 mag=17.51 sep=0.66". The closest Genie
source has ra= 236.9757 dec= -62.5655 mag=17.51 sep=0.66".
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 141 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 15:47:54.17 = 236.97569
DEC(J2000) = -62:33:55.8 = -62.56549
with a 90%-confidence error radius of about 0.62 arc sec. This position is 0.66
arc sec. from the center of the XRT error circle. The estimated magnitude is
17.51 with a 1-sigma error of about 0.14. No correction has been made for the
expected extinction corresponding to E(B-V) of 0.287.
