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
