  We report for the first time the stellar atmospheric parameters for a a set
of post-AGB stars classified by Suarez et al. (2006). The stellar spectra were
taken from optical region, with low-resolution and have different spectral
ranges. We select a sample of 70 objects with A-K spectral types and
luminosities I and Ie. The large majority of these objects have been scarcely
studied and are located toward the galactic south pole region. We employ a set
of empirical relationships that use pseudo-equivalent widths like spectral
feature to estimate effective temperature, surface gravity and metallicity. The
criteria chosen for selection of absorption are similar to employed by MK
classification system.
