  The NA48 collaboration has measured the amplitude of the CP-conserving
component of the decay KS --> pi+ pi- pi0 relative to KL --> pi+ pi- pi0. For
the characteristic parameter lambda, the values Re(lambda) = 0.038 +/-0.010 and
Im(lambda) = -0.013 +/- 0.007 have been extracted. These values agree with
earlier measurements and with theoretical predictions from chiral perturbation
theory.
