Table 9 The spin matrix element $r_{00}^{04}$ and the ratio of cross sections for longitudinally and transversely polarised photons, R = σ _L /σ _T , as a function of |t| for two values of Q², averaged over the Q² and W bins given in the table. The first uncertainty is statistical, the second systematic.
