srclist paragraph message for exposure 2 of trigger 972030
------ Start for Possible Stand-alone Circular ----
In response to GRB200513 (Swift/BAT trigger 972030) at 14:55:27 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of nominal 250.000 seconds with the U filter
starting 314 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 none of the BAT error circle. No correction has been made for
the expected extinction corresponding to E(B-V) of 0.40.

UVOT exposure began at MET 611074866.67142 or about 2020:134:15:01:01 UT
Found 935 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 13% of the srclist region. Found 72 sources in
srclist catalog. Found 28 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.)
