Table 3.

Nominal abundance uncertainties in dex (except y: by number).

Quantity	Uncertainty
y	0.015
log ϵ(C II)	0.15
log ϵ(N II)	0.20
log ϵ(Ne I)	0.10
log ϵ(Mg II)	0.15 (below 20 kK)
	0.20 (above 20 kK)
log ϵ(Si II)	0.15
log ϵ(Si III)	0.30
[N/C] ^(a)	0.10

Notes. The final uncertainties may differ because the nominal values were inflated in some cases, while repeated measurements were averaged.

^(a)

Estimated from repeated measurements and not from a quadratic sum of the N and C uncertainties.
