srclist paragraph message for exposure 1 of trigger 1094950
SRCLIST PROBLEM: srclist filled telemetry buffer
------ Start for Possible Stand-alone Circular ----
In response to GRB220302 (Swift/BAT trigger 1094950) at 07:40:19 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 32463 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 0.217.

Found 1638 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 28% of the srclist region. Found 190 sources in
srclist catalog. WARNING -- srclist catalog buffer filled. Found 42 srclist
source(s) without IDs. There are 0 good candidate(s) in the srclist catalog.
Good candidates must be brighter than 19.22 mag.
Found 26 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 20.25 mag. Found 2544 stars in largest star

Genie image analysis:
Found 114362.7 counts in the large background region of 5415.0 pixels or a rate
of 21.120 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 19.52 mag. for a
4-arcsec aperture.
Found 4145.4 counts in the XRT position region of 197.0 pixels or a rate of
21.043 counts/pixel in a radius of 8.0 arcsec. The net count rate (using local
background region) at the XRT position is -1.289 +/- 0.475 (1-sigma) cps. The
3-sigma UL at the XRT position is 1.424 cps or 19.22 mag. The number of srclist
sources filled the available telemetry. The weakest source detected was 19.03
mag. The closest srclist source has ra= 301.4300 dec= 49.3901 mag=16.98
sep=11.22". The closest Genie source has ra= 301.4299 dec= 49.3902 mag=15.56
