VizieR Online Data Catalog: GRB 111209A GROND and UVOT light curves (Kann+, 2018)

GROND g', r', i', z', J, H, Ks and UVOT uvw2, uvm2, uvw1, u, b, v, white bands photometry of GRB 111209A. The file grond.dat contains 7 columns with: mid-time of the observation [ks after the GRB trigger], mid-time of the observation [d after the GRB trigger], AB magnitude not corrected for extinction [mag], magnitude error [mag], exposure time of the observation [s], seeing [arcsec], filter The file uvot.dat contains 7 columns with: mid-time of the observation [ks after the GRB trigger], mid-time of the observation [d after the GRB trigger], AB magnitude not corrected for extinction [mag], positive magnitude error [mag], negative magnitude error [mag], exposure time of the observation [s], seeing [arcsec], filter All data are in AB magnitudes and not corrected for Galactic foreground extinction.

Midtimes are derived logarithmically, t=10^{([log(t(1)-t(0))+log(t(2)-t(0))]/2)}, hereby t(1.2) are the absolute start and stop times, and t(0) is the Swift trigger time. To obtain Vega magnitudes, it is uvw2_AB-uvw2Vega=1.73mag, uvm2_AB-uvm2Vega=1.69mag, uvw1_AB-uvw1Vega=1.51mag, u_AB-uVega=1.02mag, b_AB-bVega=-0.13mag, v_AB-vVega=-0.01mag, white_AB-whiteVega=0.80mag for UVOT data (as given at https://swift.gsfc.nasa.gov/analysis/uvot_digest/zeropts.html), and g'_AB-g'Vega=-0.062mag, r'_AB-r'Vega=0.178mag, i'_AB-i'Vega=0.410mag, z'_AB-z'Vega=0.543mag, J_AB-JVega=0.929mag, H_AB-HVega=1.394mag, Ks_AB-KsVega=1.859mag for GROND data. Corrections for Galactic extinction are, using E(B-V)=0.017 (Schlegel et al., 1998ApJ...500..525S) and the Galactic extinction curve of Cardelli et al. (1989ApJ...345..245C): A_uvw2=0.134mag, A_uvm2=0.150mag, A_uvw1=0.119mag, A_u=0.085mag, A_b=0.066mag, A_v=0.053mag, A_white=0.084mag, A_g'=0.066mag, A_r'=0.046mag, A_i'=0.034mag, A_z'=0.025mag, A_J=0.015mag, A_H=0.010mag, A_Ks=0.006mag.
