srclist paragraph message for exposure 2 of trigger 1436759
------ Start for Possible Stand-alone Circular ----
In response to GRB260111 (Swift/BAT trigger 1436759) at 09:01:23 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 875 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 BAT 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 0.111.

Found 561 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 5% of the srclist region. Found 36 sources in
srclist catalog. Found 1 srclist source(s) without IDs. There are 0 good
candidate(s) in the srclist catalog. Good candidates must be brighter than
18.66 mag.
All AG candidates sorted by magnitude for the current finding chart.
