Precision Stellar Catalogs and the Role of Anomalous Refraction.
Abstract
The current status of the University of Maryland program to evaluate the use of Two Color Refractometry (TCR) for the determination of precise stellar positions is discussed. Various aspects of the components of the program are considered in detail. The fabrication and operational progress with the hardware components is reviewed. A series of critical preliminary tests with TCR equipment operated on the 48-inch telescope have been conducted. The schedule for the various items of equipment which have been purchased and those which are being fabricated in-house is proceeding well. The technical and schedule aspects of several possible problem areas are discussed. A modification of the budget, which will have no cost or schedule impact, is being submitted separately to the Office of Naval Research to alleviate some of the above problems. (Author)
