Notes. The FWHM velocity dispersion of the Ca II K lines is also given. (a) Stars with FEBs.(b)The line of sight towards these two stars does not traverse any ISM cloud in the Colorado model but it passes within 20° of several clouds. Among these, cloud G is the closest one in velocity to these stars. (c) Upper limits are shown for those stars without Na non-photospheric absorption. (d)Names within parentheses are ISM clouds in the Colorado model (Redfield & Linsky 2008). (e) The velocity dispersion for this absorption is highly variable, and the value shown here is the value obtained from the median spectra.
