CH₃OH RATRAN model parameters.

Model #	n_{< 100 AU}^a profile	X _inner ^b	X _outer ^c

1	n ∝ r^-1.5	10^-10	10^-10
2	n ∝ r^-1.5	10^-8	10^-10
3	n = constant	10^-8	10^-10
4	n = constant	10^-8	10^-12

Notes.

^(a)

Density profile at r< 100 AU. The density profiles at r > 100 AU follow n ∝ r^-1.5 in all models.

^(b)

CH₃OH abundance profile in the hot inner envelope, r<r_{100
K} (where T > 100 K).

^(c)

CH₃OH abundance profile at r>r_{100
K} (where T< 100 K).
