srclist paragraph message for exposure 2 of trigger 1153670
------ Start for Possible Stand-alone Circular ----
In response to GRB230210 (Swift/BAT trigger 1153670) at 05:52:15 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 250 seconds with the U filter starting
285 seconds after the BAT trigger. No credible afterglow candidate has been
found in the initial data products. Data from the 2.7'x2.7' sub-image are not
available at this time. The 8'x8' region for the list of sources generated
on-board covers 100% of the BAT error circle. The list of sources is typically
complete to about 18.0 mag. No correction has been made for the expected
extinction corresponding to E(B-V) of 0.298.

UVOT exposure began at MET 697701451.19482 or about 2023:041:05:57:26 UT
Found 364 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 3% of the srclist region. Found 28 sources in
srclist catalog. Found 15 srclist source(s) without IDs. There are 0 good
candidate(s) in the srclist catalog. Good candidates must be brighter than
17.56 mag.
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.)
