II/47       Scanner Abundance in late-type evolved stars   (Spinrad+ 1969)

Scanner abundance studies. I. An investigation of super-metallicity in late-type evolved stars. Spinrad H., Taylor B.J. <Astrophys. J., 157, 1279 (1969)> =1969ApJ...157.1279S
ADC_Keywords: Abundances; Colors; Stars, late-type; Spectrophotometry Description: Abundance parameters have been derived from scanner observations of 229 stars. Observations were made with the Wampler photoelectric spectrum scanner (Wampler, 1966) on Lick Observatory's Crossley and 120inch telescopes. Data reductions were performed at UC Berkeley on the IBM 7094 computer using programs by L.V. Kuhi and B.J. Taylor. The method of reduction and the photometric standard system are described by Spinrad and Taylor (1969AJ.....72..320S). The file "color.dat" (tables 5 and 6 in the publication) gives colors between 3880 and 7400Å for program stars and survey stars, normalized so that I(5360)=1000. The file "block.dat" gives the blocking fractions for program stars. File Summary:

Note (1): w quantity w = 1-r0/r, where: r0 is the no-feature, no-background value of the index, obtained either from observations of the very metal-poor stars HD 122563 and HD 165195 or, in the case of Ca II (8662Å), from the assumption that the continuum in the neighborhood of the line is flat. r is defined as r=Ia/If or r=(Ia+Ib)/2If, where If is the color at the passband containing the feature being measured, and Ia and Ib are colors at the continuum points flanking the feature.
