srclist paragraph message for exposure 1 of trigger 1070157
IMAGE PROBLEM: no overlap
------ Start for Possible Stand-alone Circular ----
In response to GRB210824 (Swift/BAT trigger 1070157) at 04:10:01 UT,
---- UVOT paragraph for Joint or Stand-alone Circular ----
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 310 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 none of
the XRT error circle. The 8'x8' region for the list of sources generated
on-board covers 100% of the XRT 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 0.037.

UVOT exposure began at MET 651471340.05104 or about 2021:236:04:15:35 UT
Found 193 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 4% of the srclist region. Found 33 sources in
srclist catalog. Found 1 srclist source(s) without IDs. There are 0 good
candidate(s) in the srclist catalog. Good candidates must be brighter than
19.22 mag.
Found 4 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 20.75 mag. Found 49 stars in largest star catalog for
Genie image region. The stars will eliminate afterglows from about 4% of the
Genie image region.
Genie image analysis:
Found 51485.5 counts in the large background region of 6093.0 pixels or a rate
of 8.450 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 20.01 mag. for a
4-arcsec aperture. The closest srclist source has ra= 232.0962 dec= 11.1625
mag=19.71 sep=46.92". The closest Genie source has ra= 232.1158 dec= 11.1301
mag=19.25 sep=91.14".
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.)
