SPECMATCH-EMP library stellar spectra (red, top five spectra) that most closely match the shifted, normalized PFS “template” spectrum of GJ 9827 (HIP 115752, blue, bottom spectrum), and the “best-fit” linear combination of HIP 15095 with weight 0.517 and HD 201092 with weight 0.483 (green, second from bottom spectrum). Also at the very bottom of the figure in black is the residual spectrum between the “best fit” and observed spectra.
