Murison began looking into the issue of refraction through the Earth's atmosphere, which will be a new project with various applications within AA and elsewhere at USNO. He had already done some work on differential chromatic refraction and variations wrt TPH in his days at CfA, for the POINTS project. Sections of that work should be useful here as well.
Murison consulted with Hajian for the dFTS project. It appears we might have a substantial number of nights on the Steward Observatory 2.3-meter telescope, for which the adaptive optics guider that Murison designed will be needed.
