Scientific paper

A detailed analysis of the G type supergiant AZ 369 in the Small Magellanic Cloud is presented. The analysis is based on high dispersion spectrograms obtained with the Lallemand-Duchesne electronic camera installed at the echelle spectrograph of the ESO 1.52 m telescope. Spectra are interpreted with the aid of model atmospheres. An abundance of -0.4 + or -0.3 dex for Fe, Cr, and Ti is derived with respect to the sun. The possible difference between this result and the abundance derived for oxygen from gaseous nebulae is discussed.
