Consistent radial velocities of classical Cepheids from the cross-correlation technique

Simon Borgniet, Pierre Kervella, Nicolas Nardetto +11

Accurate radial velocities ($v_{\mathrm{rad}}$) of Cepheids are mandatory within the context of distance measurements via the Baade-Wesselink technique. The most common $v_{\mathrm{rad}}$ de…
