Abstract:
   Twenty-one optical absorption features, 11 of which have been
   previously defined, are automatically measured in a sample of 460
   stars. Following Gorgas et al., the indices are summarized in fitting
   functions that give index strengths as functions of stellar
   temperature, gravity, and [Fe/H]. This project was carried out with
   the purpose of predicting index strengths in the integrated light of
   stellar populations of different ages and metallicities, but the data
   should be valuable for stellar studies in the Galaxy as well. Several
   of the new indices appear to be promising indicators of metallicity
   for old stellar populations. A complete list of index data and
   atmospheric parameters is available in computer-readable form.

Note (1): Name1 and Name2 could be :
       "HR" numbers (Bright Star Catalog; Hoffleit 1982),
       "BD" (Bonner Durchmusterung) numbers,
       "Gl" numbers (Nearby Stars; Gleise 1969),
       cluster names (see the Appendix of the printed paper),
       or common names.  This is not a complete cross-reference list.
Note (2): This number is the upper limit to the actual number of measurements
       which went into the index averages, as some portions of some spectra
       were missing or otherwise unusable.
Note (3): See the author-supplied documentation, file tablea1.doc, for a
       complete list of references.
     There are 2 references in r_[Fe/H] for HD 114762
