The filter is WHITE
There are 26 detected source(s) for 020117
Bright star catalog has no entries brighter than 12 mag
*** WARNING -- no XRT distances are available.
Mean distance difference (CAT_DELTA) for 26 matched entries is 0.502" for 020117
Mean and std. dev of mag. difference (MAG_DELTA) are 0.919 and 0.310 for 020117
Found 0 entries without IDs and 0 entries that are acceptable afterglow candidates for 020117.
Acceptable entries have no ID, BAT distance < 200" or XRT distance < 10", and are > ~(80 - 10*(mag-6))" from any bright star.
Magnitude criteria will be applied later.
BAT distances are from RA=133.7040 (08:54:48.96) DEC=20.1080 (+20:06:28.8)
XRT distances are as reported in catalog file.
Good candidates have no ID, acceptable profiles,
mag between 9.01 and 18.66, BAT distances < 200",
are > ~(80 - 10*(mag-6))" from any bright star, and have had duplicates removed.
SUMMARY: 0 good candidate(s) found.
srclist paragraph message for exposure 1 of trigger 020117
------ Start for Possible Stand-alone Circular ----
In response to GRB091028 (Swift/BAT trigger 020117) at 17:00:00 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 858 seconds after the BAT trigger. No credible afterglow candidate has
been found in the initial data products. Results 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 0.03.

UVOT exposure began at MET 278442863.86846 or about 2009:301:17:14:21 UT
Found 409 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 4% of the srclist region. Found 69 sources in
srclist catalog. 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.
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.)
