srclist paragraph message for exposure 1 of trigger 981957
THIS MESSAGE IS *NOT* READY FOR DISTRIBUTION.
MORE ANALYSIS IS REQUIRED TO DETERMINE WHETHER THERE IS AN AFTERGLOW CANDIDATE.
IMAGE PROBLEM: high density of stars
SRCLIST PROBLEM: high density of stars, srclist filled telemetry buffer
See notes for more details.
WARNING -- because of the LARGE EXTINCTION, results should be used cautiously.
------ Start for Possible Stand-alone Circular ----
In response to GRB200711 (Swift/BAT trigger 981957) at 11:04:36 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 169 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. Because of the density of catalogued stars, further
analysis is required to report an upper limit for any afterglow in the
sub-image. The 8'x8' region for the list of sources generated on-board covers
100% of the XRT error circle. Because of the density of catalogued stars,
further analysis is required to report an upper limit for any afterglow in the
region. No correction has been made for the large, but uncertain, extinction
expected.

UVOT exposure began at MET 616158471.37292 or about 2020:193:11:07:46 UT
Found 4278 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 104% of the srclist region. Found 190 sources
in srclist catalog. WARNING -- srclist catalog buffer filled. Found 19 srclist
source(s) without IDs. There are 0 good candidate(s) in the srclist catalog.
Good candidates must be brighter than 19.22 mag.

Genie image analysis:
Found 78510.6 counts in the large background region of 4516.0 pixels or a rate
of 17.385 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 19.80 mag. for a
4-arcsec aperture.
Found 3204.8 counts in the XRT position region of 203.0 pixels or a rate of
15.787 counts/pixel in a radius of 8.0 arcsec. The net count rate (using large
background region) at the XRT position is -2.162 +/- 0.387 (1-sigma) cps. The
3-sigma UL at the XRT position is 1.160 cps or 19.62 mag. The number of srclist
sources filled the available telemetry. The weakest source detected was 18.88
mag. The closest srclist source has ra= 285.9680 dec= -0.1496 mag=17.95
sep=12.06". The closest Genie source has ra= 285.9745 dec= -0.1457 mag=18.76
sep=16.14".
This paragraph is only useful if the XRT position is grossly wrong. There are 1
candidate(s) in the srclist data with mag < 18.66 inside the BAT error region,
but outside the XRT error region. The brightest such source is at RA=286.01405
(19:04:03.37), DEC=-0.11097 (-00:06:39.5) (J2000). It has a mag of 18.38. It is
161.0" from the BAT position.
****THIS SOURCE IS OUTSIDE XRT ERROR CIRCLE--USE WITH CAUTION***
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 169 seconds after the BAT trigger. There is a candidate afterglow in
the list of sources generated on-board at
RA(J2000) = 19:04:03.37 = 286.01405
DEC(J2000) = -00:06:39.5 = -0.11097
with a 90%-confidence error radius of about 1.10 arc sec. The estimated
magnitude is 18.38 with a 1-sigma error of about 0.35. No correction has been
made for the large, but uncertain, extinction expected.
