Attenuation in the V band (A_V) as a function of redshift in four stellar mass bins for star-forming galaxies color-coded with their V − J color. The white squares show the median in stellar mass bins, and the error bars show the statistical uncertainty ($\sigma /\sqrt{N}$). The solid black lines show the spline-percentile regression, and the dashed lines show the 16−84 percentiles of the distribution. The diamonds highlight submillimeter-selected galaxies. In the top left corner of each panel we show the median (16−84)/2 percentile ranges of the posterior distributions of A_V and redshift as provided by EAZY.
