A new, large-scale map of interstellar reddening derived from HI emission

Daniel Lenz, Brandon S. Hensley, Olivier Doré

We present a new map of interstellar reddening, covering the 39\% of the sky with low {\rm HI} column densities ($N_{\mathrm{HI}}<4\times 10^{20}\mathrm{c}{\mathrm{m}}^{-2}$ or $E(B-V)\approx 45\rm\…
