Radiative correction to <strong>the</strong> last<br />

data from SLAC, <strong>of</strong> Andivahis et al.<br />

Dashed lines at bottom: raw data,<br />

no radiation correction.<br />

Solid line: after full radiative<br />

correction (but no two hard photons)<br />

Dotted line: <strong>the</strong> slope from <strong>the</strong><br />

double polarization experiment<br />

GEp(I) Jones et al/Punjabi et al and<br />

GEp(II) Gayou et al/Puckett et al.<br />

Note that rad. corrections<br />

systematically increases <strong>the</strong> slope<br />

(which here is G Ep 2 /τ).<br />

All two-photon corrections are<br />

ε-dependent and tend to decrease<br />

<strong>the</strong> slope.<br />
