Three-dimensional view of the molecular gas to stellar mass ratio ﹩{\mu }_{\mathrm{molgas}}﹩ as a function of lookback time and stellar mass. Data points are colored by their offsets from the MS (﹩{\rm{\Delta }}\mathrm{MS}﹩): purple is below the MS, green is on the MS, and yellow is above the MS. (This interactive figure is only available in the online journal, where the reader can rotate/zoom/shift the view to see how the data points are distributed in 3D.)
