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 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.

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.
