We recently modeled the orbital phase variations of the He emission lines of the B2e&sdO shell binary ϕ Per. The angular velocity law used for that study is found to be not correct. We repeated the whole study using a Keplerian velocity law. The application of a Keplerian velocity has only impact on the emission disk radii which are about 50% larger at 15 with respect to our previously used velocity law. All other conclusions remain valid.
