Mean magnetic field modulus estimates from the Ce III 16133 Å and Ca II 16654 Å lines in the APOGEE H-band spectra. The relatively magnetically insensitive unknown line at 15 335 Å is shown in order to demonstrate that it is well fit by a single Gaussian with FWHM = 21 km s⁻¹ during the low-〈B〉 epochs. For Ce III 16133 Å and Ca II 16654 Å, the triple Gaussians each have the same FWHM = 21 km s⁻¹. The associated 〈B〉 estimates are given below each line profile, but it is important to note that the low-〈B〉 values are highly uncertain due to the magnetic splitting being unresolved at APOGEE’s resolution .
