Overview of the VMC tiles used for this study and the proper motion results.

Tile	Central coordinates		Position Angle	Number	Time baseline	Number	μ_αcos(δ)	μ_δ
	RA_J2000 (deg)	Dec_J2000 (deg)	(deg)	of epochs	(months)	of SMC stars	(mas yr⁻¹)	(mas yr⁻¹)

Total						1 587 119	1.087 ± 0.192	−1.187 ± 0.008

Notes. Theuncertainties refer to the systematic errors, the statistical errors are of the order of 0.003−0.009 mas yr⁻¹ per tile in both directions.
