The M _{H I}–M _B relation for blue galaxies at z ∼ 0.35: The solid blue circles show our estimates of ﹩\langle \mathrm{log}({{\rm{M}}}_{{\rm{H}}\,{\rm\small{I}}})\rangle ﹩ values in blue galaxies in the three M _B bins at z ≈ 0.35 plotted against the median M _B values. The error bars are estimated by jackknife resampling. The horizontal error bars show the bin widths. The solid black line shows the best-fit M _{H I}–M _B scaling relation at z ≈ 0.35, while the blue shaded region shows the 68% confidence interval around the scaling relation. The red dashed line indicates the M _{H I}–M _B relation at z ≈ 0 (Dénes et al. 2014).
