The VRI Cousins photometric system

Basic Reference

Cousins A.W.J. 1976, Mem. R. Astr. Soc. 81, 25


Mean values of V-R(KC) and V-I(KC), measured with a Qantacon photomultiplier, are given for 1425 stars south of +10 declination. These means have been compared with published photometry in other similar systems to obtain colour transformations.
