------ Start for Possible Stand-alone Circular ----
In response to GRB230816 (Swift/BAT trigger 1185673) at 16:08:48 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 250 seconds with the U filter starting
306 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 0.312.

position found.
*** Warning -- BAT and XRT error circles do NOT overlap.
UVOT exposure began at MET 713895266.23786 or about 2023:228:16:14:21 UT
Found 2488 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 22% of the srclist region. Found 190 sources in
srclist catalog. WARNING -- srclist catalog buffer filled. Found 44 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 15 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 20.62 mag. Found 220 stars in largest star
catalog for Genie image region. The stars will eliminate afterglows from about
21% of the Genie image region. The XRT position was OUTSIDE the star catalog
search region.
Genie image analysis:
Found 12969.6 counts in the large background region of 6159.0 pixels or a rate
of 2.106 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 19.88 mag. for a
4-arcsec aperture. The number of srclist sources filled the available
telemetry. The weakest source detected was 18.92 mag. The closest srclist
source has ra= 328.4472 dec= 37.8575 mag=18.28 sep=10.25". The closest Genie
source has ra= 328.3958 dec= 37.8401 mag=18.37 sep=151.44".
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.)
