srclist paragraph message for exposure 2 of trigger 960102
IMAGE PROBLEM: no overlap
------ Start for Possible Stand-alone Circular ----
In response to GRB200306 (Swift/BAT trigger 960102) at 22:50:39 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the U filter starting
875 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
XRT error circle. The 8'x8' region for the list of sources generated on-board
covers 100% of the XRT 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 0.02.

Found 474 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 4% of the srclist region. Found 105 sources in
srclist catalog. Found 84 srclist source(s) without IDs. There are 0 good
candidate(s) in the srclist catalog. Good candidates must be brighter than
17.84 mag.
Found 9 source(s) in Genie image catalog. Found 6 Genie image source(s) without
IDs. There are 0 good candidate(s) in the Genie image catalog. Good candidates
must be brighter than 20.23 mag. Found 57 stars in largest star catalog for
Genie image region. The stars will eliminate afterglows from about 5% of the
Genie image region.
Genie image analysis:
Found 9557.1 counts in the large background region of 6196.0 pixels or a rate
of 1.542 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 19.71 mag. for a
4-arcsec aperture. The closest srclist source has ra= 198.5569 dec= 11.2847
mag=18.33 sep=54.82". The closest Genie source has ra= 198.5705 dec= 11.2706
