  We continue the study of the first sample of shear-selected clusters (Wittman
et al. 2006) from the initial 8.6 square degrees of the Deep Lens Survey (DLS,
Wittman et al. 2002); a sample with well-defined selection criteria
corresponding to the highest ranked shear peaks in the survey area. We aim to
characterize the weak lensing selection by examining the sample's X-ray
properties. There are multiple X-ray clusters associated with nearly all the
shear peaks: 14 X-ray clusters corresponding to seven DLS shear peaks. An
additional three X-ray clusters cannot be definitively associated with shear
peaks, mainly due to large positional offsets between the X-ray centroid and
the shear peak. Here we report on the X-ray properties of the 17 X-ray
clusters. The X-ray clusters display a wide range of luminosities and
temperatures; the Lx-Tx relation we determine for the shear-associated X-ray
clusters is consistent with X-ray cluster samples selected without regard to
dynamical state, while it is inconsistent with self-similarity. For a subset of
the sample, we measure X-ray masses using temperature as a proxy, and compare
to weak lensing masses determined by the DLS team (Abate et al. 2009; Wittman
et al. 2014). The resulting mass comparison is consistent with equality. The
X-ray and weak lensing masses show considerable intrinsic scatter (~48%), which
is consistent with X-ray selected samples when their X-ray and weak lensing
masses are independently determined.
