These lines range in wavelength from 2250 - 3280 {\\AA} and originate in levels ranging in energy from 38459 - 47626 cm-1. In addition, we report branching fractions for 10 weak blue lines connecting to the z4Do term which range in wavelength from 4173 - 4584 {\\AA}. The BFs are combined with radiative lifetimes from the literature to determine transition probabilities and log(gf) values.
