The Southern Vilnius Photometric System. IV - The E region standard stars
This paper is the fourth in a series on the extension of the Vilniusphotometric system to the Southern Hemisphere. Observations were made of60 stars in the Harvard Standard E regions to increase a set of standardstars.

Secondary standards for the Stromgren UVBY system
Observations of 158 E region stars have been made in the Stromgrensystem, using the 46-cm reflector at Cape Town. They are mostly brighterthan eighth magnitude and are intended for use as secondary standardsfor the four-color system. The E region relative zero points are definedwith a precision of + or - 0.001 mag, and the internal standard errorsof the colors life between + or - 0.001 and + or - 0.002 mag.

The dwarf star content of elliptical and lenticular galaxies
Near-IR spectra of 14 galaxies are analyzed to determine accurate lowermain-sequence dwarf light contributions and to set limits on themass-to-light (M/L) ratios. While dwarf light contributes 30-50 percentof the total at 8200 A, low measured FeH indices preclude contributionsof more than 15 percent to the integrated light at 9900 A from late Mdwarfs. M/L ratios of about 6 are found, consistent with dynamicalestimates. The brighter galaxies exhibit substantial gradients in theequivalent width of the Na I feature. This is at least partly due tometal abundance gradients also reflected in the TiO index, but there issome evidence for concentrations of metal-rich dwarfs toward the centersof giant galaxies.

Differential population synthesis of early-type galaxies. I - Spectrophotometric atlas of synthesis standard spectra
Continuous spectrophotometry has been obtained for 200 objects at aresolution of 10-17 A over the wavelength region 3600-10,000 A.Kron-Cousins BVRI colors are computed from the spectra and compared withpublished photoelectric photometry. The (V - R)C color index is used togroup the individual observations to form synthesis standard spectra for48 common spectral types. The standard groups include a solar abundancesequence of most spectral types and luminosity classes, metal-rich andmetal weak G - K giant-branch sequences, and horizontal-branch giants.The variations with color, luminosity, and metallicity of severalprominent line strengths are discussed. The spectral atlas is availableas a FITS magnetic tape.

UBV photometry of E region standard stars of intermediate brightness
Photometry data are given for 335 stars in the nine E regions.Observations were made using a photometer and filters on the 47 cmreflector at Cape Town. The stellar dispersions are summarized. Data arepresented in tabular form.
