Example of line-profile fitting for star 1363. The upper panel shows the result for the Na I 5682.633 Å, and the bottom panel shows the fit for the Al I 6698.673 Å line. The black lines correspond to the observed spectra. The solid red line shows the best-fit solution as the median. For comparison purposes, we also plot the best-fit solution with a variation of ±0.15 (solid cyan and magenta lines) and the spectrum without the element abundance (green line).
