  We measured the angular diameters of 44 stars with the Navy Precision Optical
Interferometer, obtaining uncertainties on the limb darkened diameter of 2% or
less for all but four stars. We then used our diameters with Gaia or Hipparcos
parallaxes to calculate each star's physical radius. We gathered information
from the literature to determine bolometric flux and luminosity, and combined
that with our diameters to produce an effective temperature. Our sample
consists of mostly giant stars, and spans a wide range of spectral classes from
B to M.
