Abstract (from CDS):

48 supergiants and bright giants have been observed in order to investigate the sodium enrichment of their atmospheres and its connection with stellar gravity. We present the equivalent widths of the 6154Å and 6160Å NaI lines measured from the program spectra, the results of effective temperature determinations, the NLTE sodium abundances, and the derived relation between the sodium overabundance and surface gravity.
