Spatial distribution of density of energetic electrons with energy E> 25 keV deduced from observations (, black crosses). The spatial distributions of calculated with the diffusive transport model of Kontar et al. (2014), with A_LT = 26 Mm², d = 5.5 Mm, n = 9.5 × 10¹⁰ cm^-3, and λ = 1.4 × 10⁸ cm (red lines), are also plotted. The looptop source is shifted 3.2 Mm in regards to the top of the loop, as described in Kuznetsov & Kontar (2015). A detailed description is provided in Sect. 4.1.
