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.
