Notes. Columns 1–7 show the line information, Col. 8 shows the equivalent width measured in the solar disc-centre intensity, and Col. 9 specifies the free parameter that is adjusted so as to match the theoretical equivalent widths to the observed ones. Final columns show the elemental abundances inferred from the different models. Blended transitions within the same branch were in some cases combined together. The NH lines are all in the R branch with three unresolved components. The listed transition probabilities are for the middle component, and the measured equivalent width has been reduced by a factor of three. Two lines of each system are shown; the full table is available at the CDS.
