a–d Measured two-color phase-resolved photoelectron energy spectra at the emission angles of θ = 0°, 45°, 90° and 135°, respectively. e–h Calculated two-color phase-resolved energy spectra by SFA model at the emission angles of θ = 0°, 45°, 90° and 135°, respectively. The blue arrow on the top denotes the direction of the rotating 400 nm field vector. The red arrow indicates the polarization direction of 800 nm linearly polarized field.
