Resulting spatially integrated X-ray DOP and flux spectra for injected beamed electron distributions with EH = 100 keV without turbulent scattering, and with turbulent scattering (using λs, 0 = 2 × 108 cm or λs, 0 = 2 × 109 cm) situated in the coronal loop over a distance of [−10″, +10″] from the loop apex. Each use the following identical electron and plasma properties of: δ = 5, Ec = 20 keV (vertical grey dotted line), a beamed distribution and Ṅ = 7 × 1035 e s−1, and coronal plasma properties of: n = 3 × 1010 cm−3 and T = 20 MK, plotted for a flare located at a heliocentric angle of θ = 60°. All DOP spectra include an albedo component and a coronal thermal component (EM = 0.9 × 1048 cm−3). The results suggest that a lack of coronal turbulent scattering could be detectable from the DOP spectrum.
