The relation between optical extinction and hydrogen column density in the galaxy.

GUVER T. and OZEL F.

Abstract (from CDS):

A linear relation between the hydrogen column density (NH) and optical extinction (AV) in the Galaxy has long been observed. A number of studies found differing results in the slope of this relation. Here, we utilize the data on 22 supernova remnants that have been observed with the latest generation X-ray observatories and for which optical extinction and/or reddening measurements have been performed and find NH(/cm2) = (2.21±0.09)x1021AV(mag). We compare our result with the previous studies and assess any systematic uncertainties that may affect these results.
