Abstract

This paper is one of a pair in which temperatures and metallicity catalogs for class IV-V stars are considered. The temperature catalog described here is derived from a calibration based on stellar angular diameters. If published calibrations of this kind are compared by using color-index transformations, temperature-dependent differences among the calibrations are commonly found. However, such differences are minimized if attention is restricted to calibrations based on Johnson V-K. A calibration of this sort from Di Benedetto (1998) is therefore tested and adopted. That calibration is then applied to spectroscopic and photometric data, with the latter predominating. Cousins R-I photometry receives special attention because of its high precision and low metallicity sensitivity. Testing of temperatures derived from the calibration suggests that their accuracy and precision are satisfactory, though further testing will be warranted as new results appear. These temperatures appear in the catalog as values of theta xi 5040 /T (effective). Most of these entries are accompanied by measured or derived values of Cousins R-I. Entries are given for 951 stars.
