Paul Kuin (MSSL/UCL) reports on behalf of the Swift/UVOT team:
In our previous report (Kuin & Melandri, GCN Circ 29787) we made
an error computing T0, which affected our T_start and T_stop times.
Below are the corrected values.
Preliminary 3-sigma upper limits using the UVOT photometric system
(Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the first
finding chart (FC) exposure and subsequent exposures are:
Filter T_start(s) T_stop(s) Exp(s) mag 3-sigma UL
v 1070 1095 19 >17.0
b 4967 5055 85 >19.7
u 4763 4960 197 >19.9
w1 4556 4755 197 >19.3
m2 4349 4548 197 >19.4
w2 1059 1071 12 >17.0
