Tabulated data of electron properties in acetylene (C2H2) at 293.15 K obtained by Monte Carlo simulations using the recommended electron collision cross section data of M.-Y. Song et al. , https://doi.org/10.1063/1.4976569. The data table includes the reduced electric field, E/N [Td], and the electron properties mean electron energy, U_e [eV], flux drift velocity, w [m/s], bulk drift velocity, W [m/s], 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}].
