Abstract : This grant has supported the development of infrared interferometry, studies of atmospheric transmission and image distortion, and the resolution and study of stars and material surrounding them, with the general goal of improving astrometry and hence determination of stellar positions. Substantial progress has been made, including determination of atmospheric distortions of infrared transmission and its variation with time, altitude location of major atmospheric distortions, correlation of radio and infrared measurements, and studies of possible change in apparent positions of stars due to stellar behavior. Findings are outlined briefly in this report. Rather complete discussion of the findings are in the 36 scientific publications supported by the grant. They are listed here and identified as to which of the several goals of the investigation they primarily apply.
