  The data points for low-<nH> paths are scattered more widely than those for denser sight lines, because O/H ratios for such paths shorter than 800 pc are generally about 0.10 dex lower than the values for longer ones.

Usage notes

Used both to refer to the function ${\\displaystyle \\mathrm {dex} (x)=10^{x}}$ and the number of (possibly fractional) orders of magnitude separating two numbers. ${\\displaystyle \\log _{10}(5)\\approx 0.70}$ and ${\\displaystyle \\log _{10}(8)\\approx 0.90}$ , so the ratio of 8 to 5 is about 0.20 dex.
