We analyzed the discrepancy of the angular dependence of strong-field ionization for CO2 among the different theoretical calculations and experiments. Using a more accurate ground-state wave function of CO2 in the asymptotic region, we showed that the accuracy in the earlier tunneling ionization theory of Tong et al. Phys. Rev. A 66 033402 (2002)] is much improved. We also concluded that the angular dependence deduced from the experiment of Pavičić et al. Phys. Rev. Lett. 98 243001 (2007)] appears to be too narrowly distributed.
