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, 1966ApJ...137..280W) on Lick Observatory's
Crossley and 120in 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 7400{AA} for program stars and survey stars, normalized so
that I(5360)=1000. The file "block.dat" gives the blocking fractions
for program stars.

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 (8662{AA}), 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.
