Basic parameters of the atmospheres (i.e.,
, 
, [ 
] , 
)
of four late type giant stars α Ari, α Boo, α Cas,
β Gem are obtained by matching synthetic spectra to
observed ones. We used model atmosphere
to compute the synthetic spectrum. The parameters of the model
atmosphere and of the
synthetic spectrum are fitted to match the observed spectrum,
accelerated by means of a proposed numerical tool.
