A simple algorithm is presented which transforms two closed orbits observed at beam position monitors around a ring into {beta} and {phi} values at the monitors. The procedure assumes the prior use of a second algorithm to measure {beta}{sub c} and {phi}{sub c} at the two dipole correctors used to excite the perturbed closed orbits. Test results from the program BETA, written to measure {beta} around the Tevatron, are shown. The sensitivities of the measurement to monitor digitisation and to quadrupole errors between the reference correctors are estimated. 4 figs.
