srclist paragraph message for exposure 1 of trigger 1093592
SRCLIST PROBLEM: srclist filled telemetry buffer
------ Start for Possible Stand-alone Circular ----
In response to GRB220117 (Swift/BAT trigger 1093592) at 16:18:51 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 161 seconds after the BAT trigger. No credible afterglow candidate has
been found in the initial data products. The 2.7'x2.7' sub-image covers 100% of
the XRT error circle. The typical 3-sigma upper limit has been about 19.6 mag.
The 8'x8' region for the list of sources generated on-board covers 100% of the
XRT error circle. The list of sources is typically complete to about 18 mag. No
correction has been made for the expected extinction corresponding to E(B-V) of
0.028.
