Notes. All data are in AB magnitudes and not corrected for Galactic foreground extinction. Midtimes were derived with the geometric mean of start and stop times. t = sqrt[(t₁ − t₀)×(t₂ − t₀)], hereby t_1.2 are the absolute start and stop times, and t₀ is the Swift trigger time. To obtain Vega magnitudes, it is uvw2_AB − uvw2_Vega = 1.73 mag, uvm2_AB − uvm2_Vega = 1.69 mag, uvw1_AB − uvw1_Vega = 1.51 mag, u_AB − u_Vega = 1.02 mag, b_AB − b_Vega = −0.13 mag, v_AB − v_Vega = −0.01 mag, and white_AB − white_Vega = 0.80 mag (as given at http://swift.gsfc.nasa.gov/analysis/uvot_digest/zeropts.html). Corrections for Galactic extinction are, using E_{(B − V)} = 0.080 mag (Schlafly & Finkbeiner 2011) and the Galactic extinction curve of Cardelli et al. (1989): A_uvw2 = 0.728 mag, A_uvm2 = 0.763 mag, A_uvw1 = 0.539 mag, A_u = 0.405 mag, A_b = 0.328 mag, A_v = 0.256 mag, and A_white = 0.397 mag.
