------ Start for Possible Stand-alone Circular ----
In response to GRB180721 (Swift/BAT trigger 849018) at 11:06:48 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 250 seconds with the U filter starting
119 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 100% of the
XRT error circle. The typical 3-sigma upper limit has been about 19.2 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 18.0 mag. No
correction has been made for the expected extinction corresponding to E(B-V) of
0.07.

XRT position found for srclist. XRT position found for Genie image. BAT
position found.
UVOT exposure began at MET 553864149.51586 or about 2018:202:11:09:04 UT
Found 876 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 7% of the srclist region. Found 190 sources in
srclist catalog. WARNING -- srclist catalog buffer filled. Found 140 srclist
source(s) without IDs. There are 0 good candidate(s) in the srclist catalog.
Good candidates must be brighter than 18.12 mag.
Found 2 source(s) in Genie image catalog. 1 source(s) are within 10.0" of the
xrt position. 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
20.53 mag. Found 40 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 15268.3 counts in the large background region of 6194.0 pixels or a rate
of 2.465 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 20.02 mag. for a
4-arcsec aperture.
Found 957.8 counts in the XRT position region of 199.0 pixels or a rate of
4.813 counts/pixel in a radius of 8.0 arcsec. The net count rate (using local
background region) at the XRT position is 1.832 +/- 0.129 (1-sigma) cps or
17.72 mag and a range from 17.65 to 17.80 mag. The 3-sigma UL at the XRT
position is 2.219 cps or 17.51 mag. The number of srclist sources filled the
available telemetry. The weakest source detected was 19.87 mag.
Found 1 srclist source(s) within 10.0" of the XRT position.
The brightest such source has ra= 347.7126 dec= 4.8584 mag=17.93 sep=6.67".
The closest srclist source has ra= 347.7126 dec= 4.8584 mag=17.93 sep=6.67".
Found 1 Genie source(s) within 10.0" of the XRT position. The brightest such
source has ra= 347.7126 dec= 4.8584 mag=17.24 sep=6.66". The closest Genie
source has ra= 347.7126 dec= 4.8584 mag=17.24 sep=6.66".
Report rejected UVOT sources within 10 arcsec XRT position.
Such sources are usually NOT the afterglow.
****THIS SOURCE NEAR XRT POSITION WAS REJECTED--USE WITH CAUTION****
UVOT took a finding chart exposure of 250 seconds with the U filter starting
119 seconds after the BAT trigger. There is a candidate afterglow in the
rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 23:10:51.02 = 347.71260
DEC(J2000) = +04:51:30.2 = 4.85838
with a 90%-confidence error radius of about 0.75 arc sec. This position is 6.66
arc sec. from the center of the XRT error circle. The estimated magnitude is
17.24 with a 1-sigma error of about 0.15. No correction has been made for the
expected extinction corresponding to E(B-V) of 0.07.
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.)
(Magnitudes followed by * have been corrected for exposure.)
