Abstract:
    Temperature dependance of the abundances of the chemical elements Si,
    Ca, Cr and Fe in the atmospheres of normal, metallic-line (Am),
    magnetic peculiar (Ap) and pulsating magnetic peculiar (r0Ap) stars in
    the range 6000-15000K.

Note (1): the type use the following conventions:
    I   = normal main-sequence stars,
    II  = Am stars,
    III = Nonpulsating Ap stars,
    IV  = Pulsating r0Ap stars (the collest Ap stars)
Note (2):
    log(N/Ntot): elemental abundance relative to the total number of atoms
