We extend our previous work on the resummation of the semi-inclusive photon energy spectrum in $\\chi^0\\chi^0\\to \\gamma+X$ in the vicinity of the maximal photon energy $E_\\gamma = m_\\chi$ with NLL' accuracy from the case of narrow photon energy resolution $E^\\gamma_{\\rm res}$ of order $m_W^2/m_\\chi$ to intermediate resolution of order $E^\\gamma_{\\rm res} \\sim m_W$.
