  1. The columns give the spins of the orbitals contributing, their quantum numbers, the proton-emission Q values for the emission to the ground and first excited states, the partial potential-barrier penetration half-lives, the spectroscopic factors, and the partial proton-emission half-lives for the respective orbitals
