He <-3.50 <-3.50 -1.10
Si -3.73 -3.58 -4.53
Fe -3.19 -3.00 -4.59
Cr -4.20 -3.90 -6.40
Ti -4.54 -4.20 -7.14

Solar abundances were taken from (1). The second and the third columns give, respectively, abundances derived using the scaled-solar abundance model atmosphere (2) and using model with $T_{\rm eff}=13~750$ K, $\log g=4.2$with magnetic field included (see Sect. 3.4). Abundances are given in the logarithmic scale $\log(N_{\rm el}/N_{\rm total})$.
