List UVOT sources within 10" of the XRT position:
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 18.12, XRT distances < 6.25",
are > ~(80 - 10*(mag-6))" from any bright star, and have had duplicates removed.
SUMMARY: 0 good candidate(s) found.
srclist paragraph message for exposure 2 of trigger 1116441
THIS MESSAGE IS *NOT* READY FOR DISTRIBUTION.
MORE ANALYSIS IS REQUIRED TO DETERMINE WHETHER THERE IS AN AFTERGLOW CANDIDATE.
IMAGE PROBLEM: high density of stars
SRCLIST PROBLEM: high density of stars, srclist filled telemetry buffer
See notes for more details.
------ Start for Possible Stand-alone Circular ----
In response to GRB220715 (Swift/BAT trigger 1116441) at 22:24:42 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 250 seconds with the U filter starting
315 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. Because of the density of catalogued stars, further analysis
is required to report an upper limit for any afterglow in the sub-image. The
8'x8' region for the list of sources generated on-board covers 100% of the XRT
error circle. Because of the density of catalogued stars, further analysis is
required to report an upper limit for any afterglow in the region. No
correction has been made for the expected extinction corresponding to E(B-V) of
0.525.

UVOT exposure began at MET 679617027.2946 or about 2022:196:22:30:22 UT
Found 5000 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 41% of the srclist region. Found 190 sources in
srclist catalog. WARNING -- srclist catalog buffer filled. Found 70 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 23 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 18.63 mag. Found 781 stars in largest star
catalog for Genie image region. The stars will eliminate afterglows from about
103% of the Genie image region. The Genie image is INCOMPLETE with 12557 null
pixels.
Genie image analysis:
Found 219554.5 counts in the large background region of 2705.0 pixels or a rate
of 81.166 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 17.91 mag. for a
4-arcsec aperture.
Found 46273.3 counts in the XRT position region of 151.0 pixels or a rate of
306.446 counts/pixel in a radius of 8.0 arcsec. The net count rate (using local
background region) at the XRT position is 151.728 +/- 0.886 (1-sigma) cps or
12.72 mag and a range from 12.71 to 12.73 mag. The 3-sigma UL at the XRT
position is 154.385 cps or 12.70 mag. The number of srclist sources filled the
available telemetry. The weakest source detected was 18.28 mag. The closest
srclist source has ra= 254.8647 dec= -33.5913 mag=17.28 sep=39.38". The closest
Genie source has ra= 254.8760 dec= -33.6030 mag=19.28 sep=19.16".
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
