Scientific paper

Absolute flux measurements of eight G, K, and early M stars in the 1.2-5.5 micron region, have been compared with fluxes computed for model stellar atmospheres. The stellar angular diameter obtained from fitting the fluxes at 3.5 microns are in good agreement with observational values and with angular diameters deduced from the relation between visual surface brightness and V - R color. The temperatures obtained from the shape of the flux curves are in satisfactory agreement with other temperature estimates. Theoretical strengths of lines in the fundamental CO band appear to be too weak as compared to the first overtone lines.
