srclist paragraph message for exposure 1 of trigger 945521
IMAGE PROBLEM: multiple afterglow candidates,
------ Start for Possible Stand-alone Circular ----
In response to GRB191221 (Swift/BAT trigger 945521) at 20:39:13 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 91 seconds after the BAT trigger. There is a candidate afterglow in
the list of sources generated on-board at
RA(J2000) = 10:19:19.17 = 154.82986
DEC(J2000) = -38:09:30.6 = -38.15849
with a 90%-confidence error radius of about 1.10 arc sec. This position is 3.3
arc sec. from the center of the XRT error circle. The estimated magnitude is
15.43 with a 1-sigma error of about 0.14. No correction has been made for the
expected extinction corresponding to E(B-V) of 0.08.

UVOT exposure began at MET 598653668.90306 or about 2019:355:20:41:03 UT
Found 919 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 16% of the srclist region. Found 190 sources in
srclist catalog. WARNING -- srclist catalog buffer filled. Found 58 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 20 source(s) in Genie image catalog. 2 source(s) are within 10.0" of the
xrt position. Found 6 Genie image source(s) without IDs. There are 2 good
candidate(s) in the Genie image catalog. Good candidates must be brighter than
20.60 mag. Found 149 stars in largest star catalog for Genie image region. The
stars will eliminate afterglows from about 15% of the Genie image region.
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=154.82806
(10:19:18.73), DEC=-38.15828 (-38:09:29.8) (J2000). It has a mag of 18.41. It
is 63.2" from the BAT position.
