Fig. 3
Relation between visual extinction, AV, and neutral hydrogen column density N(H i), molecular hydrogen column density N(H2), and total hydrogen column density N(Htot), computed as N(H i)+2N(H2). Note that some EDIBLES lines-of-sight are not included since no direct H i or H2 measurements are available.
