Interstellar 5889 Å NaI-D2 and 5895 Å NaI-D1 absorption lines for the stars HD 94194, HD 94266, and HD 94766. The first row shows the normalized interstellar NaI-D2 line-profile (red histogram line) superimposed on the HI emission spectrum (black histogram line). The second and third rows show the unnormalized interstellar NaI (D2 and D1, respectively) line-profiles (red histogram line) superimposed on the fit model (blue line); and the individual model components (dotted red line). For other target stars, line profiles and models can be found in Appendix A.
