image paragraph message for exposure 1 of trigger 1071765


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.

WARNING -- because of the LARGE EXTINCTION, results should be used cautiously.
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 GRB210903 (Swift/BAT trigger 1071765) at 13:53:56 UT,

---- UVOT paragraph for Joint or Stand-alone Circular ----

UVOT took a finding chart exposure of 150 seconds with the White filter
starting 166 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 large, but uncertain, extinction expected.

Unreliable extinction found for bat position. Unreliable extinction found for
xrt position. XRT position found for Genie image. BAT position found.

UVOT exposure began at MET 652370230.79026 or about 2021:246:13:57:05 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 18 source(s) in Genie image catalog. 2 source(s) are within 20.0" of the
xrt position. Found 18 Genie image source(s) without IDs. There are 0 good
candidate(s) in the Genie image catalog. Good candidates must be brighter than
19.65 mag. Found 541 stars in largest star catalog for Genie image region. The
stars will eliminate afterglows from about 56% of the Genie image region.
Found 2 Genie source(s) within 20.0" of the XRT position. The brightest such
source has ra= 186.1568 dec= -62.6787 mag=16.27 sep=13.58". The closest Genie
source has ra= 186.1568 dec= -62.6787 mag=16.27 sep=13.58".

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.)
