From
Tracey Poole at MSSL <tsp@mssl.ucl.ac.uk>
T. S. Poole (UCL-MSSL), and P. T. Boyd (NASA/GSFC) on behalf of the
Swift/UVOT team.
The Swift/UVOT began observing the field of GRB060403 (BAT Trigger=203755,
P. T. Boyd, et. al, GCN 4945) at 13:13:00 UT, 43s after the BAT trigger
(which includes the 10s V filter settling exposure). No new source is
detected at the XRT position (V. Mangano, GCN 4947) in coadded images with
any of the filters. The following 5-sigma magnitude upper limits are not
corrected for Galactic extinction; E(B-V) = 1.270.
Filter T_range(s) T_exp(s) 5sigma(mag)
V 43-10090 1220.0 19.25
B 4011-16788 1299.0 20.41
U 3807-15876 1299.0 20.16
UVW1 3602-11845 1242.6 20.18
UVM2 3397-10994 1299.4 20.59
UVW2 4421-6052 399.6 19.99
WHITE 63-17630 1329.8 20.37
Where T_range is time post-trigger, and T_exp is the exposure time of
the observation. A 6 arcsec radius was used for all filters.
