Notes. The HD 149404 data from Porras et al. (2014) come from four velocity components, while the HD 154368 and HD 183143 data come from three. The HD 183143 data from Indriolo & McCall (2012) come from two velocity components, one of which, at vLSR =7 km s−1, correspondsto a component measured by Porras et al. (2014) at v⊙ = −10 km s−1 (each component marked with an asterisk). Upper limits reported by Indriolo & McCall (2012) are expressed here as 5σ results. Values reported in the last column have been computed with the same assumptions as in Indriolo & McCall (2012). Numbers enclosed in parentheses denote the uncertainty of the last digit(s); for example, 1.2(3) ≡ 1.2 ± 0.3, whereas 4.3(2.1) ≡ 4.3 ± 2.1. (a) Values reported for these components correspond to very weak OH+ absorption components with no corresponding CH+ detections. The associated N(Htot) is likely underestimated leading to overestimated values for ζp.
