(a)The He I λ3819 is present in the primary and secondary spectrum. We note that the observed He I λ3819 line also contains the He II λ3813 line from the primary. (b)The He II λ4025 line has a strong contribution from the secondary. (c) The mean value is calculated as 
where RVi is the RV of line i and n is the total number of lines used. The errors of the mean values are calculated via Gaussian error propagation.
