Obtaining accurate radial velocities for Cepheid companions using the STIS echelles
We discuss the high dispersion echelle observations of the hot binary companions of six Cepheids with known radial-velocity orbits that we have obtained with the STIS FUV E140H mode on board the Hubble Space Telescope, with the goal of determining the masses of these Cepheids. We discuss the stabili...
