srclist paragraph message for exposure 2 of trigger 873539
SRCLIST PROBLEM: srclist filled telemetry buffer
------ Start for Possible Stand-alone Circular ----
In response to GRB181126 (Swift/BAT trigger 873539) at 09:54:08 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 250 seconds with the U filter starting
292 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
0.07.

UVOT exposure began at MET 564919162.21108 or about 2018:330:09:59:17 UT
Found 1246 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 11% of the srclist region. Found 190 sources in
srclist catalog. WARNING -- srclist catalog buffer filled. Found 88 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 9 source(s) in Genie image catalog. Found 5 Genie image source(s) without
IDs. There are 0 good candidate(s) in the Genie image catalog. Good candidates
must be brighter than 20.00 mag. Found 126 stars in largest star catalog for

Genie image region.
Genie image analysis:
Found 40520.5 counts in the large background region of 6197.0 pixels or a rate
of 6.539 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 19.49 mag. for a
4-arcsec aperture.
Found 1342.1 counts in the XRT position region of 203.0 pixels or a rate of
6.611 counts/pixel in a radius of 8.0 arcsec. The net count rate (using local
background region) at the XRT position is 0.162 +/- 0.159 (1-sigma) cps or
20.35 mag and a range from 19.61 to 24.56 mag. The 3-sigma UL at the XRT
position is 0.639 cps or 18.87 mag. The number of srclist sources filled the
available telemetry. The weakest source detected was 18.36 mag. The closest
srclist source has ra= 152.3419 dec= -29.6862 mag=17.56 sep=21.22". The closest
Genie source has ra= 152.3417 dec= -29.6866 mag=16.45 sep=21.43".
This paragraph is only useful if the XRT position is grossly wrong. There are 2
candidate(s) in the image data with mag < 19.44 inside the BAT error region,
but outside the XRT error region. The brightest such source is at RA=152.34173
(10:09:22.02), DEC=-29.68657 (-29:41:11.7) (J2000). It has a mag of 16.45. It
is 39.8" from the BAT position.
