Upper panel: comparison of the blue-violet spectra of the mCP star LAMOST J065647.94+242958.8 (#732; TYC 1898-1408-1; manual type: A0 V SiSrCr; MKCLASS final type: B9.5 V Sr) to the liblamost A0 V standard spectrum. Lower panel: comparison of the blue-violet spectra of the mCP star LAMOST J052816.11−063820.1 (#344; TYC 4765-708-1; manual type: kA1hA9mA9 SrCrEu; MKCLASS final type: kA1hA8mA9 SrEu) to the liblamost F0 V standard spectrum. Some prominent lines of interest are indicated. We note the weak Ca II K line with a peculiar profile and the unusual profile of the Hϵ line in LAMOST J052816.11−063820.1.
