image paragraph message for exposure 2 of trigger 1046414



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

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

In response to GRB210502 (Swift/BAT trigger 1046414) at 17:39:33 UT,

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

UVOT took a finding chart exposure of 150 seconds with the White filter
starting 861 seconds after the BAT trigger. There is a candidate afterglow in
the rapidly available 2.7'x2.7' sub-image at
RA(J2000) = 18:03:02.77 = 270.76156
DEC(J2000) = -29:49:49.8 = -29.83050
with a 90%-confidence error radius of about 0.61 arc sec. This position is 8.1
arc sec. from the center of the XRT error circle. The estimated magnitude is
15.70 with a 1-sigma error of about 0.14. No correction has been made for the
large, but uncertain, extinction expected.

Unreliable extinction found for bat position. Unreliable extinction found for
xrt position. XRT position found for Genie image. BAT position found.

UVOT exposure began at MET 641670861.40928 or about 2021:122:17:54:16 UT
No information found about the number of stars in the star catalog for srclist
region.

Found 63 source(s) in Genie image catalog. 2 source(s) are within 10.0" of the
xrt position. Found 30 Genie image source(s) without IDs. There are 1 good
candidate(s) in the Genie image catalog. Good candidates must be brighter than
19.86 mag. Found 931 stars in largest star catalog for Genie image region. The
stars will eliminate afterglows from about 100% of the Genie image region.

This paragraph is only useful if the XRT position is grossly wrong. There are 7
candidate(s) in the image data with mag < 19.30 inside the BAT error region,
but outside the XRT error region. The brightest such source is at RA=270.74434
(18:02:58.64), DEC=-29.82805 (-29:49:41.0) (J2000). It has a mag of 15.57. It
is 36.9" from the BAT position.
