Linear-correlation analysis for the plots in Figs. 8 and 9.

Ratio ra Pb

Na i-CO 0.984 2%
Ca i-CO 0.946 7%
Mg i-CO 0.866 17%
H2-CO 0.826 21%

Linear-correlation coefficient, r, between the log-log values of the line intensities plotted in Figs. 8 and 9. Zero corresponds to no correlation, unity to complete correlation.


Probability, P, that a random sample of measured line intensities could produce a linear-correlation coefficient, r, equal to the value listed in the second column (Bevington & Robinson 1992). P should be less than a few percent if a correlation exists between the measured line intensities.
