Scientific paper

Using the Palomar Testbed Interferometer (PTI), angular diameters have been measured for over 60 giant and supergiant stars, ranging in spectral type from B7 to M5. Analysis of night-to-night variations in the data reveal a consistency in the reduced results at the 1.3% level; comparison of PTI data to previous investigations with IOTA, CERGA, and lunar occultations show good agreement between the results. In combination with existing photometry and Hipparcos distances for these objects, we have determined effective temperatures and linear radii for these objects; temperatures range from 20,000K to 3,500K, radii range from 5 to 110 solar radii. The dependence of these two parameters upon spectral type, luminosity class and V-K color is explored for consistency with and departures from expected trends.
