 |  | Binary star measurements made at Pic-du-Midi The 2-m Pic-du-Midi telescope has been used to obtain 130 visualmeasurements of 64 very close binaries. The measurements were made withan illuminated cross wire micrometer which provided magnificationfactors of 2500 to 5000. Data are presented in tabular form for suchmeasurements as total visual magnitude, angular position andseparations, and period.
