17. We adopt the v-e cross section calculations reported in J.N. Bahcall, M. Kamionkowsky, and A. Sirlin, Phys. Rev. D 51, 6146 (1995). See also M. Passera, hep-ph/0011190, for recent refined calculations of O(a) QED corrections to v-e scattering.
18. We adopt the v-d CC cross section as reported in the computer code DiFFCROSS.FOR [9,12], and corresponding to the "Kubodera-Nozawa" calculation option. See also S. Nakamura, T. Sato, V. Gudkov, and K. Kubodera, Phys. Rev. C 63, 034617 (2001), for recent refined calculations of v-d cross sections.
19. In the present work, the width of the S K energy resolution function is taken to be ±15% for an electron (kinetic) energy 10 MeV, as in [14]. Such value, which is in agreement with the SK calibration results graphically reported in [6], scales with energy as described in [12,13].
20. In the present work, the width of the SNO energy resolution function is taken to be ±11% for an electron (kinetic) energy of 10 MeV, as in [12]. Such value is in agreement with the preliminary SNO electron energy calibration results (~9 photomultiplier hits/MeV, as reported in [11]). The value previously adopted in [15] (on the basis of the SNO prospective estimates available at that time) was somewhat larger (±14%).
