Notes.

(a)

see Nieva (2013);

(b)

ε( ∑ CNO) = log (ΣCNO/H) + 12, using ADS abundances for C, N and O from NP12 (stars 1–20) and NS11 (stars 21–26);

(c)

by mass fraction;

(d)

m/u: atmosphere mixed/unmixed with CN-processed material;

(e)

inferred polar field strength for the observed dipolar B-field (oblique magnetic rotator).
