srclist paragraph message for exposure 2 of trigger 814259
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.
------ Start for Possible Stand-alone Circular ----
In response to GRB180314 (Swift/BAT trigger 814259) at 19:11:31 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of nominal 250.000 seconds with the U filter
starting 308 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 expected
extinction corresponding to E(B-V) of 0.23.
