srclist paragraph message for exposure 1 of trigger 020118
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: srclist filled telemetry buffer

------ Start for Possible Stand-alone Circular ----
In response to GRB091029 (Swift/BAT trigger 020118) at 15:28:00 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of nominal 150 seconds with the White filter
starting 855 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 coverage of the XRT error circle by the 8'x8'
region for the list of sources generated on-board is uncertain because the
large number of sources filled the available telemetry. No correction has been
made for the expected extinction corresponding to E(B-V) of 0.02.

Found 491 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 4% of the srclist region. Found 190 sources in
