of spectral type A-M. These include a relatively isolated Brackett line (H4-11), 5 neutral metals, and 3 molecular bands. In Table \[ftshband\], we define 9 narrow band indices with bandpasses ranging from 10 to 50 cm$^{-1}$, which include each of these features. The variable widths of the bandpasses were selected to minimize line blending, contamination from residual telluric absorption, and sensitivity to radial velocity shifts. Table \[ftshband\] also identifies the wavenumber of the dominant contributor and the lower state energy level, the central wavenumber and passband of the index, and additional species which may contribute to the index strength. The equivalent widths of these 9 indices were evaluated from the normalized spectra of our 85 survey stars, and are tabulated in Tables  \[ftshewsup\] to  \[ftshewdw\] in units of cm$^{-1}$ [^5]. Uncertainties in these equivalent widths depend on the SNR of the spectrum in question and the bandpass/strength of the feature. Errors range from $\sigma_{EW} = 0.02-0.1$ cm$^{-1}$ exceeding this upper limit in very few cases. Multiple observations of several sources are listed for comparison.

The temperature and luminosity dependence for four representative indices is illustrated in Figure \[fig7\]. The 4–11 Brackett line (HI5950) behaves as expected, with a rapid rise
