Notes. Normal font denotes features identified by the MKCLASS_mCP code (Hümmerich et al. 2020), bold font the additional lines used for the identification of CP3 stars by the MKCLASS_HgMn code. The columns denote: (1) Blend/Line. (2) Wavelength (Å). (3) Spectral range in which the corresponding feature was probed. At the resolution of the LAMOST low-resolution spectra, all features listed in Table 2 are, to some extent, blended with other absorption lines. Nevertheless, the specified elements generally constitute the main contributors to these blends in the investigated groups of CP stars.
