**Table 2:** Cen X-4 dynamical parameters.
Reference	$\gamma$	K₂	P
	(km s^-1)	(km s^-1)	(d)
Cowley et al. (1988)	$234\pm 8$	$152\pm 10$	-
McClintock & Remillard (1990)	$137\pm 17$	$146\pm 12$	0.629063
Torres et al. (2002)	$184.0\pm 1.9$	$150.0\pm 1.1$	$0.6290496\pm 0.0000021$
This paper	$196.0\pm 1.1$	$145.8\pm 1.0$	$0.630\pm0.001$

The velocity values reported here have been obtained by fixing P to the value given by Torres et al. (2002). We also repeated the fit leaving all the parameters free, obtaining the value given here.
