Open Access

Table 3

Best-fit parameters of the broken line model of the three cores and H-MM1 (Pineda et al. 2022).

Parameter	L694-2^(★)	L429	L1517B^(★)	H-MM1	Unit
a	1.3(0.4)	1.3 (1.1)	1.6(0.6)	2.0	× 10⁻⁸
b	−0.5(6.0)	−1.6(4.6)	−1.0(3.3)	1.1	× 10¹⁴ cm⁻²
c	–	0.73(6.6)	–	−1.1	× 10⁻⁸
x₀	–	7.5(2.0)	–	2.6	× 10²² cm⁻²

Notes. ^(★) A linear relation is fitted to L1517B and L694-2 instead of the broken line model. Uncertainty of the parameter is listed in brackets, in percentage units with respect to the best-fit value.
