srclist paragraph message for exposure 1 of trigger 811167
WARNING -- because of the LARGE EXTINCTION, results should be used cautiously.
------ Start for Possible Stand-alone Circular ----
In response to GRB180222 (Swift/BAT trigger 811167) at 00:20:27 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 104 seconds with the White filter
starting 1867 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. The list of sources is
typically complete to about 18 mag. No correction has been made for the large,
but uncertain, extinction expected.
