Abstract

We determine and tabulate A[λ]/AK, the wavelength dependence of interstellar extinction, in the Galactic plane for 1.25µm ≤ λ ≤ 8.0µm along two lines of sight: l = 42 ◦ and l = 284 ◦. The first is a relatively quiescent and unremarkable region; the second contains the giant H II region RCW 49 as wel...
