srclist paragraph message for exposure 1 of trigger 1404295
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: 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 GRB251015 (Swift/BAT trigger 1404295) at 14:17:23 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 870 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 0.00% of the BAT error circle. No correction
has been made for the large, but uncertain, extinction expected.

UVOT exposure began at MET 782231551.22078 or about 2025:289:14:32:26 UT
Since the srclist star catalog filled its buffer, the sensitivity for an
afterglow may be REDUCED. The stars will eliminate afterglows from about 66%
or more of the srclist region. Found 190 sources in srclist catalog. WARNING --
srclist catalog buffer filled. Found 131 srclist source(s) without IDs. There
are 0 good candidate(s) in the srclist catalog. Good candidates must be
brighter than 18.66 mag.
The number of srclist sources filled the available telemetry. The weakest
source detected was 19.60 mag.
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
