τ353 as a function of NH i estimated at 30′ resolution. Each point and its associated bar is the mean and standard deviation of τ353 in bins of NH i. The solid line is the linear regression fit using pixels for which 1.2 <NHI< 2.5 × 1020 cm-2. Its parametrization is τ353 = 6.3 ± 0.1 × 10-27NH i − 0.02 × 10-6.
