Notes. [N] is our best-fitting value, Δ[N] the corresponding uncertainty, and Δ[N]cl the change in [N] (always positive) if clumping with f∞ = 0.1 is included in the models (Sect. 4.5.1). Values displayed in italics were derived by the “curve-of-growth” method. Literature values are from Walborn et al. (2004) for N11-031 and from Hunter et al. (2009) for the B-stars and N11-029. When two entries are provided, the first one corresponds to our preferred solution, except for N11-031 where we consider both solutions to be possible.
