Rate in bkg region from 0 to 45 arcsec is 11.341 counts/pixel (5-sig UL in 4" is 20.03 mag) for 020140_g297873723
Do not compute counts in XRT region because position is too far from center.
There are no candidates inside BAT error circle, but outside XRT error circle.

Good candidates have no ID, acceptable profiles,
mag between 9.01 and 20.59, XRT distances < 10",

image paragraph message for exposure 1 of trigger 020140


IMAGE PROBLEM: no overlap

WARNING -- because of the LARGE EXTINCTION, results should be used cautiously.

------ Start for Possible Stand-alone Circular ----

In response to GRB100610 (Swift/BAT trigger 020140) at 00:00:00 UT,

---- UVOT paragraph for Joint or Stand-alone Circular ----

UVOT took a finding chart exposure of 150 seconds with the White filter
starting 2517 seconds after the LAT 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 none of the XRT error circle. No correction has been
made for the large, but uncertain extinction expected.

UVOT exposure began at MET 297873723.44776 or about 2010:161:14:42:01 UT

Found 3302 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 57% of the srclist region. Found 190 sources in
srclist catalog. WARNING -- srclist catalog buffer filled. Found 56 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 27 source(s) in Genie image catalog. Found 1 Genie image source(s)
without IDs. There are 0 good candidate(s) in the Genie image catalog. Good
candidates must be brighter than 20.59 mag. Found 509 stars in largest star
catalog for Genie image region. The stars will eliminate afterglows from about
46% of the Genie image region. The XRT position was OUTSIDE the star catalog
search region.

Genie image analysis:
Found 68667.9 counts in the large background region of 6055.0 pixels or a rate
of 11.341 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 20.03 mag. for a
4-arcsec aperture. The closest srclist source has ra= 295.9997 dec= 27.3275
mag=19.06 sep=1331.85". The closest Genie source has ra= 295.9413 dec= 27.3550

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.)
