srclist paragraph message for exposure 1 of trigger 020135
------ Start for Possible Stand-alone Circular ----
In response to GRB100414 (Swift/BAT trigger 020135) at 02:20:22 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of nominal 150 seconds with the White filter
starting 58764 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 0.02.

Found 181 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 4% of the srclist region. Found 23 sources in
srclist catalog. Found 0 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.
(U/V/White SRCLIST mags < 17.5/17.5/18.5 are reliable. Mag > 18.5/18.5/19.5 are
