------ Start for Possible Stand-alone Circular ----
In response to GRB100713 (Swift/BAT trigger 020143) at 14:36:32 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 6246 seconds after the INTEGRAL trigger. No credible afterglow
candidate has been found in the initial data products. The 2.7'x2.7' sub-image
covers 100% of the XRT error circle. The typical 3-sigma upper limit has been
about 19.6 mag. 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 mag. No correction has been made for the expected extinction
corresponding to E(B-V) of 0.06.

Found 422 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 7% of the srclist region. Found 62 sources in
srclist catalog. Found 2 srclist source(s) without IDs. There are 0 good
candidate(s) in the srclist catalog. Good candidates must be brighter than
19.22 mag.
Found 10 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 20.94 mag. Found 59 stars in largest star
catalog for Genie image region. The stars will eliminate afterglows from about
6% of the Genie image region.
Genie image analysis:
Found 36816.8 counts in the large background region of 6186.0 pixels or a rate
of 5.952 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 20.38 mag. for a
4-arcsec aperture.
Found 1186.8 counts in the XRT position region of 197.0 pixels or a rate of
6.024 counts/pixel in a radius of 8.0 arcsec. The net count rate (using local
background region) at the XRT position is 0.047 +/- 0.247 (1-sigma) cps or
23.09 mag and a range from 21.11 to 99.99 mag. The 3-sigma UL at the XRT
position is 0.788 cps or 20.04 mag. The closest srclist source has ra= 255.1994
dec= 28.3851 mag=19.57 sep=33.88". The closest Genie source has ra= 255.1992
