srclist paragraph message for exposure 2 of trigger 1095288
SRCLIST PROBLEM: srclist filled telemetry buffer
------ Start for Possible Stand-alone Circular ----
In response to GRB220306 (Swift/BAT trigger 1095288) at 18:15:37 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 250 seconds with the U filter starting
301 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
0.578.

UVOT exposure began at MET 668283667.9557 or about 2022:065:18:21:02 UT
Found 2887 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 23% of the srclist region. Found 190 sources in
srclist catalog. WARNING -- srclist catalog buffer filled. Found 68 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 13 source(s) in Genie image catalog. 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 20.03 mag. Found 227 stars in largest star

22% of the Genie image region.
Genie image analysis:
Found 37332.8 counts in the large background region of 6086.0 pixels or a rate
of 6.134 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 19.32 mag. for a
4-arcsec aperture.
Found 1199.7 counts in the XRT position region of 199.0 pixels or a rate of
6.029 counts/pixel in a radius of 8.0 arcsec. The net count rate (using large
background region) at the XRT position is -0.084 +/- 0.141 (1-sigma) cps. The
3-sigma UL at the XRT position is 0.422 cps or 19.11 mag. The number of srclist
sources filled the available telemetry. The weakest source detected was 18.42
mag. The closest srclist source has ra= 5.4008 dec= 71.3504 mag=18.30
sep=49.96". The closest Genie source has ra= 5.3991 dec= 71.3700 mag=19.69

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.)
