srclist paragraph message for exposure 2 of trigger 1194500
SRCLIST PROBLEM: srclist filled telemetry buffer
------ Start for Possible Stand-alone Circular ----
In response to GRB231104 (Swift/BAT trigger 1194500) at 01:47:39 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 860 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 19.6 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
0.156.

3-sigma UL at the XRT position is 0.701 cps or 19.99 mag. The number of srclist
sources filled the available telemetry. The weakest source detected was 19.62
mag. The closest srclist source has ra= 23.7292 dec= 83.8030 mag=18.29
sep=45.54". The closest Genie source has ra= 23.7292 dec= 83.8031 mag=16.41
sep=45.77".
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.)
