The temperature dependence of the weight for D1 (a) and D2 (b). c The quasiparticle scattering rate for D1 as a function of temperature. The solid line denotes a quadratic temperature dependence. d The temperature dependence of the quasiparticle scattering rate for D2. The dashed line is a linear fit.
