Five P I lines we selected. Observed spectra are shown in blue, and the best-fitting synthetic spectra are shown in red for two solar analogs, HIP 4909 (upper) and HIP 117367 (lower). The solid vertical line marks the line center, and the dashed vertical lines indicate the fitting range (corresponding to ±30 km s−1).
