Comparing the observed and modeled spectral and imaging diagnostics: coronal source FWHM, δ_{nV F}, γ_FP, and ﹩{\eta }_{{\rm{FP}}}^{\rm{X-ray}}﹩, from top to bottom. The acceleration regions for three different spatial functions are shown in different colors: linear spatial functions in pink, random functions in blue, and Gaussian functions in yellow. Crosses and circles show acceleration regions with and without short-timescale turbulent scattering, respectively.
