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 19.22, XRT distances < 5",
are > ~(80 - 10*(mag-6))" from any bright star, and have had duplicates removed.
SUMMARY: 1 good candidate(s) found.
srclist paragraph message for exposure 3 of trigger 819490
------ Start for Possible Stand-alone Circular ----
In response to GRB180329 (Swift/BAT trigger 819490) at 14:08:23 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 870 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 05:31:36.93 = 82.90388
DEC(J2000) = -23:41:25.8 = -23.69049
with a 90%-confidence error radius of about 0.75 arc sec. This position is 1.4
arc sec. from the center of the XRT error circle. The estimated magnitude is
16.95 with a 1-sigma error of about 0.14. No correction has been made for the
expected extinction corresponding to E(B-V) of 0.04.

UVOT exposure began at MET 544026195.33782 or about 2018:088:14:23:10 UT
Found 846 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 7% of the srclist region. Found 161 sources in
srclist catalog. Found 42 srclist source(s) without IDs. There are 1 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 7 Genie image source(s) without IDs. There are 1 good
candidate(s) in the Genie image catalog. Good candidates must be brighter than
20.74 mag. Found 57 stars in largest star catalog for Genie image region. The
stars will eliminate afterglows from about 8% of the Genie image region.
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.)
