Abstract:
    We report on the analysis of observations of Procyon obtained with the
    Multichannel Astrometric Photometer during the years 1986-2004. While
    the results significantly increase the precision of the estimated
    characteristics of the components of the system, they are generally in
    good agreement with the most recent studies.

Description:
    Procyon was placed on the Multichannel Astrometric Photometer (MAP;
    Gatewood 1987) program in October of 1986 and remained there until the
    MAP observations were discontinued in 2004.
