   • 2004, Cartledge et al 2004, The Homogeneity of Interstellar Oxygen in the Galactic Disk, Abstract, The Astrophysical Journal, Volume 613, Issue 2, pp. 1037-1048,

     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.
