The spectra have been normalized by a maximum flux (minimum absorption) spectrum. This is obtained by determining the maximum flux at each velocity to produce a minimum absorption spectrum. This spectrum is then used to normalize all of the spectra shown in the figure. This normalization has the desirable property that it makes all changes appear as absorptions.
A complete overview of the project is now published in ApJ, 452, L53, along with articles describing the results for HD 50896 (ApJ, 452, L57), HD 64760 (ApJ, 452, L61), and HD 66811 (ApJ, 452, L65).
