Warm methanol mass (left column) and integrated methanol emission (right column) for various disk sizes. The various shades of green and orange are used to indicate variations in luminosity. The luminosity from low to high is indicated by the darkest to lightest color. The models plotted here have luminosities 5 × 10² L_⊙, 1 × 10⁴ L_⊙ and 5 × 10⁶ L_⊙. The dashed lines present fiducial envelope-only models with various luminosities. The solid lines present the fiducial envelope-plus-disk models with various luminosities and disk radii. The shades of orange show models with large dust grains (high mm opacity), and the shades of green show those with small grains (low mm opacity).
