[en] The purpose of this note is to determine the acceptability of the PEP Prototype Quadrupole 127Q780 profile for use in all quadrupoles except Q2 and Q3. The dependence of the betatron frequency upon the particle energy and betatron amplitude has been determined for the case where the nonlinear field impurities of the 127Q780 are present in the following quadrupoles: Q1, QF1, QD1, QF2, QF, QD, QF3, QD2, QS1 and QS2. It was assumed that quadrupoles Q2 and Q3 were perfect with no nonlinear field impurities. The method used to calculate the values of the betatron frequencies has been reported elsewhere and we present only the results. The tune shifts given here are due to only the nonlinear fields in the quadupoles and do not include those due to the natural chromaticity of the lattice or the correcting sextupoles
