A brief account of the early results of this study was given in D. Reznik et al., J. Low Temp. Phys. 131, 417 (2003). The strong temperature dependence of particular phonons described in Ref. 17 was not yet discovered at the time of this publication.

note
-
We note that there is a systematic difference between the data of Ref. 15 and our data of about 1 meV which we attribute to a slightly different calibration of the neutron spectrometers. Our calibration is supported by the good agreement with the optical data of Ref. 21.

note
-
We completely agree with Ref. 15 with regard to the a-b anisotropy of the zone-center bond stretching modes. On the other hand, we disagree with Ref. 15 with regard to the anisotropy of the softening at the zone edge: we find that the frequencies are more strongly renormalized in the b direction than in the a direction. We note that the a axis zone boundary mode at E = 66 meV was ignored in Ref. 15 when evaluating the a-b anisotropy-in spite of the correct observation that this mode carries an appreciable spectral weight. This leads to a substantial overestimate of the renormalization along a.

note
-
We note that the tentative assignment of weak peaks observed in Ref. 15 at energies ≈70 meV and ≈61 meV, respectively, to the chain O modes and to c-axis displacements of apical O has to be interchanged.
