Best physical parameters derived from the χ² minimization for IRAS 16293–2422 A/B.

Component	N (cm⁻²)	T_kin (K)	FWHM (km s⁻¹)	V_LSR (km s⁻¹)	Size (")	n(H₂) (cm⁻³)	ortho/para
Hot corino	(6.95	± 0.03) × 10¹⁶	90*	5.0*	3.88^*	1.0^*	1.0x10^8*	3.0^*
Warm envelope	(8.55	± 0.12) × 10¹³	50*	2.64 ± 0.03	3.72^*	20.0^*	1.0x10^6*	3.0^*
Cold envelope	(4.11	± 0.01) × 10¹³	10*	0.65*	4.05^*	100.0^*	1.0x10^5*	3.0^*

Notes. The values marked with a * symbol were fixed during the modeling. The derived column densities correspond to the ortho form of H₂CO. The column density of the para-form can be computed by multiplying by the ortho/para ratio = 3.
