Masses of 582 neutron-deficient nuclides (30 ≤ Z ≤ 85) were measured with time-resolved Schottky mass spectrometry at the FRS-ESR facility at GSI, 117 were used for calibration. The masses of 71 nuclides were obtained for the first time. A typical mass accuracy of 30 μu was achieved. These data have entered the latest atomic mass evaluation. The mass determination of about 140 additional nuclides was possible via known energies (Q-values) of α-, β-, or proton decays. The obtained results are compared with the results of other measurements.
