Table 6

Estimated accuracy of the derived MWSC cluster parameters

Parameter	Internal error	External error

Proper motion	± 0.5 mas/yr (δ > −20°)	±0.8 mas/yr
	± 0.8 mas/yr (δ < −20°)
Distance	−	11%
E(B − V)	−	7%
Age¹	25%, (log t < 8.2)	39%
	10%, (log t > 8.2)
Tidal radius	25%	−
Radial velocity²	±1.0 km s^-1	−

Notes.

⁽¹⁾

Only 637 clusters have derived internal errors in the catalogue.

⁽²⁾

75% of clusters have ε_RV < 5.0 km s^-1 (for more details, see text).
