Table 1

Expectation values and standard deviations of the marginalised posterior distributions of free parameters of the model defined in Eqs. (3) and (4).

σ_p [km s⁻¹]	α	β	p
539 ± 16	0.63 ± 0.05	− 0.49 ± 0.38	0.88 ± 0.015

Notes. Parameters listed above are for the fiducial model; the self-similar evolution model, with β set to zero, returns identical central values and errors for the other parameters and so are not listed.
