XIII (Hartkopf+ 1996) ftp://ftp.chara.gsu.edu/ : results from CHARA project Interferometry Stars, double and multiple Five hundred sixty-five measurements of 99 binary star systems are presented, obtained during 1984-1986 by means of speckle interferometry at the 1.8 m Perkins telescope on Anderson Mesa, Arizona. These observations were collected as part of a systematic program in which frequent speckle observations of nearby binary systems were to be used to attempt the detection of unseen companions through the analysis of residual motions in wide, visual binaries. This is the first of several papers in which these observations are presented and discussed.
