srclist paragraph message for exposure 3 of trigger 873539


SRCLIST PROBLEM: srclist filled telemetry buffer
1 source(s) near the XRT position were rejected as afterglow candidate(s). See
notes for details.

------ 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 150 seconds with the White filter
starting 868 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
0.07.

Found 1200 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 105 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 11 source(s) in Genie image catalog. 1 source(s) are within 10.0" of the
xrt position. 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
19.93 mag. Found 123 stars in largest star catalog for Genie image region. The
stars will eliminate afterglows from about 13% of the Genie image region.

Genie image analysis:
Found 222490.6 counts in the large background region of 5909.0 pixels or a rate
of 37.653 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 19.38 mag. for a
4-arcsec aperture.
Found 7896.5 counts in the XRT position region of 199.0 pixels or a rate of
39.681 counts/pixel in a radius of 8.0 arcsec. The net count rate (using local
background region) at the XRT position is 2.911 +/- 0.636 (1-sigma) cps or
18.62 mag and a range from 18.41 to 18.89 mag. The 3-sigma UL at the XRT
position is 4.820 cps or 18.07 mag. The number of srclist sources filled the
available telemetry. The weakest source detected was 18.74 mag. The closest
srclist source has ra= 152.3401 dec= -29.6902 mag=16.79 sep=27.95".
Found 1 Genie source(s) within 10.0" of the XRT position. The brightest such
source has ra= 152.3491 dec= -29.6852 mag=17.95 sep=8.27". The closest Genie
source has ra= 152.3491 dec= -29.6852 mag=17.95 sep=8.27".

This paragraph is only useful if the XRT position is grossly wrong. There are 6
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=152.36126
(10:09:26.70), DEC=-29.70598 (-29:42:21.5) (J2000). It has a mag of 18.08. It
is 102.3" 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 868 seconds after the BAT trigger. There is a candidate afterglow in
the list of sources generated on-board at
RA(J2000) = 10:09:26.70 = 152.36126
DEC(J2000) = -29:42:21.5 = -29.70598
with a 90%-confidence error radius of about 1.10 arc sec. The estimated
magnitude is 18.08 with a 1-sigma error of about 0.35. No correction has been
made for the expected extinction corresponding to E(B-V) of 0.07.

Report rejected UVOT sources within 10 arcsec XRT position.
Such sources are usually NOT the afterglow.

****THIS SOURCE NEAR XRT POSITION WAS REJECTED--USE WITH CAUTION****
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 868 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 10:09:23.78 = 152.34910
DEC(J2000) = -29:41:06.8 = -29.68523
with a 90%-confidence error radius of about 0.63 arc sec. This position is 8.27
arc sec. from the center of the XRT error circle. The estimated magnitude is
17.95 with a 1-sigma error of about 0.15. No correction has been made for the
expected extinction corresponding to E(B-V) of 0.07.

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.)
