r_in (au)	0.4	10	0.4	10	The inner radius
r_out (au)	10⁴	5 × 10⁴	10⁴	5 × 10⁴	The outer radius of the envelope
M_E (M_⊙)	1, 3, 5	50, 300, 1000	1, 3, 5	50, 300, 1000	Envelope mass
R_D (au)	−	−	20, 50, 200	500, 1000, 2000	Disk radius
T_* (K)	5000	40000	5000	40000	Protostellar temperature
M_* (M_⊙)	0.5	30	0.5	30	Protostellar mass
L(L_⊙)	2, 8, 32	5 × 10², 10⁴, 5 × 10⁵	2, 8, 32	5 × 10², 10⁴, 5 × 10⁵	Bolometric luminosity

Notes. The fiducial model parameters are highlighted in boldface. The fiducial models are those with small dust grains. When calculating the emission lines, we assumed source distances of 150 pc and 4 kpc for low- and high-mass protostars.
