Tabulated data of electron properties in ethylene (C2H4) at 293.15 K obtained by solving the electron Boltzmann equation (BE) in density gradient (DG) representation (method BE DG) using the recommended electron collision cross section data of F. Fresnet et al., https://doi.org/10.1063/1.4976569. The data table includes the reduced electric field, E/N [Td], and the electron properties flux drift velocity, w [m/s], bulk drift velocity, W [m/s], gas number density times flux mobility, N mu_w [m^{-1}V^{-1}s^{-1}], gas number density times bulk mobility, N mu_W [m^{-1}V^{-1}s^{-1}], bulk longitudinal component of diffusion tensor times gas density, D_L N [m^{-1}s^{-1}], bulk transverse component of diffusion tensor times gas density, D_T N [m^{-1}s^{-1}], reduced effective ionization frequency, nu_eff/N [m^{3}/s], and reduced effective steady-state Townsend ionization coefficient, alpha_eff/N [m^{2}].
