image paragraph message for exposure 1 of trigger 020119
THIS MESSAGE IS *NOT* READY FOR DISTRIBUTION.
MORE ANALYSIS IS REQUIRED TO DETERMINE WHETHER THERE IS AN AFTERGLOW CANDIDATE.
IMAGE PROBLEM: partial overlap
SRCLIST PROBLEM: srclist filled telemetry buffer
See notes for more details.
------ Start for Possible Stand-alone Circular ----
In response to GRB091030 (Swift/BAT trigger 020119) at 04:43:12 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 37637 seconds after the BAT trigger. No credible afterglow candidate
has been found in the initial data products. The 2.7'x2.7' sub-image covers 25%
of the BAT error circle. The typical 3-sigma upper limit has been about 19.6
mag. The coverage of the BAT 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 0.14.

UVOT exposure began at MET 278608235.21646 or about 2009:303:15:10:33 UT
Found 2234 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 39% of the srclist region. Found 190 sources in
srclist catalog. WARNING -- srclist catalog buffer filled. Found 7 srclist
source(s) without IDs. There are 0 good candidate(s) in the srclist catalog.
Good candidates must be brighter than 18.66 mag.
Found 46 source(s) in Genie image catalog. Found 1 Genie image source(s)
without IDs. There are 0 good candidate(s) in the Genie image catalog. Good
candidates must be brighter than 19.67 mag. Found 422 stars in largest star
catalog for Genie image region. The stars will eliminate afterglows from about
40% of the Genie image region.
Genie image analysis:
Found 112391.0 counts in the large background region of 5136.0 pixels or a rate
of 21.883 counts/pixel in a radius of 45.0 arcsec. Based on this background,
the typical 5-sigma UL at a random point in the Genie image is 19.68 mag. for a
4-arcsec aperture. The number of srclist sources filled the available
telemetry. The weakest source detected was 18.93 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.)
