image paragraph message for exposure 2 of trigger 972030
IMAGE PROBLEM: no overlap
------ 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 250 seconds with the U filter starting
314 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 none of the
BAT error circle. 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.
Found 6 source(s) in Genie image catalog. Found 0 Genie image source(s) without
IDs. There are 0 good candidate(s) in the Genie image catalog. Good candidates
must be brighter than 19.70 mag. Found 118 stars in largest star catalog for
Genie image region. The stars will eliminate afterglows from about 15% of the
Genie image region.
Genie image analysis:
Found 24572.1 counts in the large background region of 6093.0 pixels or a rate
of 4.033 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 19.75 mag. for a
4-arcsec aperture.
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.)
