Summary of H₂ column densities, streamer mass, infall rate, and streamer mass relative to the disk’s mass, using the TIPSY modeled infalling time of 24.1 kyr.

Tracer	C₂H	o-c-C₃H₂	HC₃N
$N_{H_{2}}$ ${N_{{{\rm{H}}_2}}}$	≥1.17	≥4.55	≥ 0.99
(10²¹ cm ⁻²)	≥1.17	≥4.55	≥ 0.99
Streamer mass	≥4.67	≥18.3	≥ 4.76
(10⁻³ M_⊙)	≥4.67	≥18.3	≥ 4.76
Infall rate	≥1.94	≥7.57	≥ 1.97
(10⁻⁷ M_⊙/yr)	≥1.94	≥7.57	≥ 1.97
Relative mass^(†)	≥65	≥257	≥ 67
