Scientific paper

Preliminary stellar diameter measurements of 24 stars made with the Mark III optical interferometer are reported. The stellar diameters reported were obtained using 12.0 and 8.3 m baselines with a center wavelength of 674 nm and a bandwidth of 10 nm. The observed visibilities were normalized using observations of nine stars of small angular diameter. The calibrated visibilities and best-fit uniform disk models for 24 giant and supergiant stars of angular diameters 4 mas to 18 mas, with accuracies of order 0.5 mas are presented.
