BINARY PROPERTIES FROM CEPHEID RADIAL VELOCITIES (CRaV)
We have examined high accuracy radial velocities of Cepheids to determine the binary frequency. The data are largely from the CORAVEL spectrophotometer and the Moscow version, with a typical uncertainty of ⩽ 1 km s[superscript −1], and a time span from 1 to 20 years. A systemic velocity was obtained...
