srclist paragraph message for exposure 1 of trigger 848932


THIS MESSAGE IS *NOT* READY FOR DISTRIBUTION.
MORE ANALYSIS IS REQUIRED TO DETERMINE WHETHER THERE IS AN AFTERGLOW CANDIDATE.
IMAGE PROBLEM: no overlap
SRCLIST PROBLEM: high density of stars, srclist filled telemetry buffer
See notes for more details.

WARNING -- because of the LARGE EXTINCTION, results should be used cautiously.

------ Start for Possible Stand-alone Circular ----

In response to GRB180720 (Swift/BAT trigger 848932) at 22:23:57 UT,

---- UVOT paragraph for Joint or Stand-alone Circular ----

UVOT took a finding chart exposure of 150 seconds with the White filter
starting 100 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. 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 large, but
uncertain, extinction expected.

Large extinction of 6.57 found for bat position. Unreliable extinction found
for xrt position. XRT position found for srclist. XRT position found for Genie
image. BAT position found.

UVOT exposure began at MET 553818359.15784 or about 2018:201:22:25:54 UT

Found 4820 stars in largest star catalog for srclist region. The stars will
eliminate afterglows from about 86% of the srclist region. Found 190 sources in
srclist catalog. WARNING -- srclist catalog buffer filled. Found 21 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 40 source(s) in Genie image catalog. Found 3 Genie image source(s)
without IDs. There are 0 good candidate(s) in the Genie image catalog. Good
candidates must be brighter than 20.35 mag. Found 1056 stars in largest star
catalog for Genie image region. The stars will eliminate afterglows from about
106% of the Genie image region. The XRT position was OUTSIDE the star catalog
search region.

Genie image analysis:
Found 94605.1 counts in the large background region of 5354.0 pixels or a rate
of 17.670 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 19.79 mag. for a
4-arcsec aperture. The number of srclist sources filled the available
telemetry. The weakest source detected was 19.23 mag. The closest srclist
source has ra= 265.6393 dec= -26.6314 mag=19.09 sep=14.79". The closest Genie
source has ra= 265.6264 dec= -26.6111 mag=17.42 sep=71.03".

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.)
(Magnitudes followed by * have been corrected for exposure.)
