srclist paragraph message for exposure 1 of trigger 020296
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: high density of stars, srclist filled telemetry buffer
See notes for more details.
------ Start for Possible Stand-alone Circular ----
In response to GRB130904 (Swift/BAT trigger 020296) at 16:39:36 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 7170 seconds after the INTEGRAL 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 6% of the INTEGRAL error circle. Because of
the density of catalogued stars, further analysis is required to report an
upper limit for any afterglow in the region. No correction has been made for
the expected extinction corresponding to E(B-V) of 0.72.

UVOT exposure began at MET 400012758.42686 or about 2013:247:18:39:15 UT
Found 5000 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 125% of the srclist region. Found 190 sources
in srclist catalog. WARNING -- srclist catalog buffer filled. Found 93 srclist
source(s) without IDs. There are 0 good candidate(s) in the srclist catalog.
Good candidates must be brighter than 18.66 mag.
The number of srclist sources filled the available telemetry. The weakest
source detected was 19.40 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
not. Others are uncertain.)
(U/V/White Genie image mags < 18.0/18.0/19.0 are reliable. Mag > 19.0/19.0/20.0
are not. Others are uncertain.)
