Expressions for eccentricities in terms of the motion integrals are found for a model of the Galactic gravitational field. Exact formulas are used to ascertain the influence of errors in heliocentric distance, radial velocity, and proper motion on eccentricity errors. Due to the proper motion errors, there is a tendency to overestimate the values of small eccentricities (the higher they are, the greater the distance).
