Objects near Q1108 are in the upper 5 rows, and near Q1408 in the bottom 8 rows. The magnitudes are corrected for Galactic extinction. The last column gives the luminosity fraction relative to a U* galaxy at z=2, which has an apparent magnitude $U_{{\rm A}} = 24$. The uncertainties are 0.01 for this fraction.
