Tabulated data of electron swarm transport coefficients in carbon monoxide (CO) at 293.15 K obtained by Monte Carlo simulations under hydrodynamic conditions using the electron collision cross section data released by S. Biagi in Magboltz v11.11 (edition of 25 Jan 2021), https://magboltz.web.cern.ch/magboltz/. The data table includes the reduced electric field, E/N [Td], and the electron swarm transport coefficients mean energy, U_e [eV], bulk longitudinal characteristic energy, D_L/mu [eV], bulk transversal characteristic energy, D_T/mu [eV], flux drift velocity, W^* [m/s], bulk drift velocity, W [m/s], gas density times flux longitudinal diffusion coefficient, N D_L^* [m^{-1} s^{-1}], gas density times bulk longitudinal diffusion coefficient, N D_L [m^{-1} s^{-1}], gas density times flux transverse diffusion coefficient, N D_T^* [m^{-1} s^{-1}], gas density times bulk transverse diffusion coefficient, N D_T [m^{-1} s^{-1}], ionization rate coefficient, k_i [m^{3}/s], attachment rate coefficient, k_a [m^{3}/s], and reduced effective SST ionization coefficient, alpha_eff/N(Hydro) [m^{2}].
