Abstract

We have developed an algorithm to determine precise fringe phases in the presence of atmospheric turbulence. We use phase bootstrapping to improve parameter estimates of weak fringes observed on long baselines through coherent integration. With data from the Navy Prototype Optical Interferometer (NPOI) on γ Sagittae, we demonstrate the importance of this method for the study of limb-darkening of stars.
