    An extensive Δa-photometric survey of southern B and A type bright stars
    (1998) Vogt, N; Kerschbaum, F; Maitzen, HM; Faundez-Abans, M
    Photoelectric photometry of 803 southern BS objects in the aa-system as detection tool for magnetic chemically peculiar (=CP2) stars has been carried out and compared to published spectral types. The statistical yield of such objects detected by both techniques is practically the same. We show that there are several factors which contaminate the search for these stars, but this contamination is only of the order of 10% in both techniques. We find a smooth transition from normal to peculiar stars.

    Hβ photometry of southern CP2 stars
    (2000) Maitzen, HM; Paunzen, E; Vogt, N; Weiss, WW
    We present H beta photometry of 233 southern CP2 stars (covering the magnetic Ap stars according to the definition by Preston 1974) brighter than V < 8.5 mag from the list of Bidelman & MacConnell(1973).
