The relationship between ϵ and ν for moderate flares. Here, the ϵth and νth part of the inflowing energy and electron number density are tranferred into the nonthermal electrons. The long dashed and full line represent ϵ = 1.55ν and ϵ = 0.78ν according to Eq. (21) for M_{A, in} = 0.015 and 1, respectively. The dashed lines represent the relationships of Eqs. (18) and (19).
