The RS CVN Project at Capilla Peak Observatory

Abstract

The 61-cm telescope at the Capilla Peak Observatory of the University of New Mexico was used extensively from 1979 to 1982 for UBVR observations of selected RS CVn stars. (See Elston and Zeilik, 1982, for details of the system.) Complete coverage was obtained from most of the short-period systems (Hall, 1976)--RT and CG Cyg, XY Uma (the most active of these systems), UV Psc and ER Vul--with a precision of 0.01 mag or better for each datum. Our early experiences showed that these stars had rapid intrinsic variations (within a month).
