High-precision Penning-trap mass measurements of the N{approx_equal}Z{approx_equal}34 nuclides {sup 68}Se, {sup 70}Se, {sup 70m}Br, and {sup 71}Br were performed, reaching experimental uncertainties of 0.5-15 keV. The new and improved mass data together with theoretical Coulomb displacement energies were used as input for rp process network calculations. An increase in the effective lifetime of the waiting point nucleus {sup 68}Se was found, and more precise information was obtained on the luminosity during a type I x-ray burst along with the final elemental abundances after the burst.
