srclist paragraph message for exposure 1 of trigger 886486
THIS MESSAGE IS *NOT* READY FOR DISTRIBUTION.
MORE ANALYSIS IS REQUIRED TO DETERMINE WHETHER THERE IS AN AFTERGLOW CANDIDATE.
IMAGE PROBLEM: no image afterglow info
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 GRB190129 (Swift/BAT trigger 886486) at 09:20:09 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of nominal 150.000 seconds with the White
filter starting 135 seconds after the BAT trigger. No credible afterglow
candidate has been found in the initial data products. Data from the 2.7'x2.7'
sub-image are not available at this time. 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.

*** Warning -- BAT and XRT error circles do NOT overlap.
UVOT exposure began at MET 570446567.99238 or about 2019:029:09:22:42 UT
Found 2837 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 43% of the srclist region. Found 190 sources in
srclist catalog. WARNING -- srclist catalog buffer filled. Found 10 srclist
source(s) without IDs. There are 0 good candidate(s) in the srclist catalog.
Good candidates must be brighter than 19.22 mag.
The number of srclist sources filled the available telemetry. The weakest
source detected was 18.70 mag. The closest srclist source has ra= 247.8058 dec=
-47.8189 mag=16.75 sep=42.96".
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.)
(Magnitudes followed by * have been corrected for exposure.)
