Fig. 7

CC curves for the Stokes-I spectrum of stars GJ 411, GJ 388, and GJ 873 with line positions and intensities extracted from the NSO spectrum of FeH (Kitt Peak archive). 2094 lines are listed in the E-X system 6320–7400 cm⁻¹ (1.35–1.58 µm), and 1613 in the E-A system 5200-6322 cm⁻¹ (1.58–1.92µm). Laboratory data were weighted by relative intensities in both calculations.
