  We present the more refined abundances of elements (C, O, Na, Mg, Al, Si, Ca,
Sc, Ti, V, Cr, Mn, Fe, Ni, Zn, Sr, Y, Zr and Ba) determined using the
computationally intensive ATLAS12 atmosphere model for the metallic-line stars
Pi Dra and HR 7545. We compare the chemical abundances derived from ATLAS9
model atmosphere with those of derived from ATLAS12. The abundances are in
agreement with each other, within their uncertainties. We thus state that
ATLAS9 may be used for the abundance analysis of slowly rotating chemically
peculiar stars, such as Pi Dra and HR 7545.
