Chara Technical Report

In response to the accumulation of the first substantial collection of observational data from the CHARA Array, obtained during the fall of 2001, a series of Mathcad programs has been developed as a means for reducing these data to calibrated visibilities. The Mathcad tools developed to date include routines that calculate estimated visibilities for single and double stars, ephemeredes from binary star orbital elements, (u,v) plane and projected baseline coverage for target stars, and the analysis of an observational dataset to yield a mean value of raw visibility. This Technical Report describes the last of these programs and presents the results from a set of data obtained during the night of 6 Nov 2001 for the extrasolar planetary system upsilon Andromedae.
