8. When the thickness of film is comparable to the penetration depth or the magnetic field is applied parallel to the c axis, the dominant effect is the doppler shift as described in M. Aprili, E. Badica, and L. H. Greene, Phys. Rev. Lett. 83, 4630 (1999); R. Krupke and G. Deutscher, ibid. 83, 4634 (1999). In the former paper, the lack of splitting in parallel magnetic field in YBCO/Pb is mentioned.

19. The YBCO/Ag spetrum is presented to identify the difference of epitaxial and nonepitaxial junctions at 0.1 K, where the influence of the thermal smearing is quite small. At higher temperature regions (above 1 K), the peak structures of these junctions become similar form due to the thermal smearing effect.
20. The detailed fitting of the experimental spectra indicates δ=0 with accuracy better than 1 μV.
