  We systematically study three-terminal InSb-Al nanowire devices by using
radio-frequency reflectometry. Tunneling spectroscopy measurements on both ends
of the hybrid nanowires are performed while systematically varying the chemical
potential, magnetic field and junction transparencies. Identifying the
lowest-energy state allows for the construction of lowest- and zero-energy
state diagrams, which show how the states evolve as a function of the
aforementioned parameters. Importantly, comparing the diagrams taken for each
end of the hybrids enables the identification of states which do not coexist
simultaneously, ruling out a significant amount of the parameter space as
candidates for a topological phase. Furthermore, altering junction
transparencies filters out zero-energy states sensitive to a local gate
potential. Such a measurement strategy significantly reduces the time necessary
to identify a potential topological phase and minimizes the risk of falsely
recognizing trivial bound states as Majorana zero modes.
