\caption{X-ray properties of the four clumps (see Fig. \ref{fig:lss_moircs}
for the definition of the clumps).  Clump~3 is not detected in the X-ray data,
and the numbers quoted below are $3\sigma$ limits.
The coordinates correspond to the peak of the X-ray emission. 
The $L_X$ luminosity is based on the extrapolation of the detected flux to
$R_{500}$, described in \citet{finoguenov07}. The total mass is computed
using the scaling relations ($L_X-M$) with the weak lensing calibration for
mass from COSMOS, achieved at a similar redshift ($z\sim0.9$) and
luminosity range (Leauthaud et al. in prep.).
The newly discovered clumps are assumed to lie at the same redshift as the RDCSJ0910
cluster (i.e., clump~1).
