*** WARNING -- XRT position is outside star catalog search region.
Bright star catalog has no entries brighter than 12 mag
Mean distance difference (CAT_DELTA) for 4 matched entries is 0.231" for 932058_g3121
Mean and std. dev of mag. difference (MAG_DELTA) are 0.801 and 0.531 for 932058_g3121
Found 0 entries without IDs and 0 entries that are acceptable afterglow candidates for 932058_g3121.
Acceptable entries have no ID, XRT distances < 5", and are > 0.8*(80 - 10*(mag-6))" from any bright star
from any bright star and >21.6" from other rejected sources.
Magnitude criteria will be applied later.
BAT distances are from RA=352.1400 (23:28:33.60) DEC=-40.4640 (-40:27:50.4)
XRT distances are from RA=352.1614 (23:28:38.74) DEC=-40.5011 (-40:30:03.9)

There are 48249.648 counts in the bkg source region of 5973.0000 pixels.
Rate in bkg region from 0 to 45 arcsec is 8.078 counts/pixel (5-sig UL in 4" is 20.22 mag) for 932058_g3121
Do not compute counts in XRT region because position is too far from center.
There are no candidates inside BAT error circle, but outside XRT error circle.
Good candidates have no ID, acceptable profiles,
mag between 9.01 and 20.77, XRT distances < 5",
are > ~(80 - 10*(mag-6))" from any bright star, and have had duplicates removed.
SUMMARY: 0 good candidate(s) found.

image paragraph message for exposure 1 of trigger 932058
IMAGE PROBLEM: no overlap
------ Start for Possible Stand-alone Circular ----
In response to GRB191029 (Swift/BAT trigger 932058) at 11:15:20 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 3098 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
none of the XRT error circle. 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 0.02.

UVOT exposure began at MET 594043642.25496 or about 2019:302:12:07:17 UT
Found 134 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 3% of the srclist region. Found 21 sources in
srclist catalog. Found 0 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 4 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 20.77 mag. Found 14 stars in largest star catalog for
Genie image region. The stars will eliminate afterglows from about 2% of the
Genie image region. The XRT position was OUTSIDE the star catalog search
region.
Genie image analysis:
Found 48249.6 counts in the large background region of 5973.0 pixels or a rate
of 8.078 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 20.22 mag. for a
4-arcsec aperture. The closest srclist source has ra= 352.1720 dec= -40.4905
mag=17.41 sep=47.80". The closest Genie source has ra= 352.1325 dec= -40.4784
mag=20.48 sep=113.86".
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.)
