SL2SJ02141-0405		0.611	0.43
SL2SJ02180-0515	{	0.645	0.69		− ^b
SL2SJ02180-0515	{	0.649	0.23		− ^b
SL2SJ02215-0647		0.618	0.72		<3.1 ^c
SL2SJ08544-0121	{	0.351	0.45		6.3 ± 2.5
SL2SJ08544-0121	{	0.356	1.07		6.3 ± 2.5
SL2SJ08591-0345		0.642	0.53		− ^d
SL2SJ09413-1100		0.384	1.11		3.7 ± 3.4

Notes.The columns show the name of the SL2S group; spectroscopic redshift of the group, ; projected virial radius of the group, R_PV, in units of Mpc; virial mass of the group in units of 10¹⁴ M_⊙; projected mass derived from weak lensing as computed within a circular aperture of radius 2 Mpc, in units of 10¹⁴ M_⊙.

^(a)

M_WL inside a projected radius of 2 Mpc taken from Limousin et al. (2009).

^(b)

R_E is below 3 arcsec and is within galaxy lensing regime.

^(c)

The weak lensing signal is low, and only an upper limit could be established.

^(d)

The system is located at the edge of the field of view.
