$\varepsilon(X)$~$=$~$\log~(X/{\rm H})$~+~12. 
Error estimates consist of statistical 1$\sigma$-uncertainties
derived from line-to-line scatter (\# lines) plus 0.1~dex for continuum
placement uncertainty (added in quadrature);
realistic uncertainties, including systematic effects e.g. if a magnetic 
field were present, are expected to be larger.
