    "abstract": "We examine the applicability and viability of methods to obtain knowledge\nabout bound-states from information provided solely in Euclidean space.\nRudimentary methods can be adequate if one only requires information about the\nground and first excited state and assumptions made about analytic properties\nare valid. However, to obtain information from Schwinger functions about higher\nmass states, something more sophisticated is necessary. A method based on the\ncorrelator matrix can be dependable when operators are carefully tuned and\nerrors are small. This method is nevertheless not competitive when an\nunambiguous analytic continuation of even a single Schwinger function to\ncomplex momenta is available.",
