Table 4:
Single halo models. The Einstein radius is the same in the best
models for strong lensing :
.
For our two strong lensing models, the total mass inside this radius is
.
Errors due to
uncertainties in arcs redshift are omitted. Also reported previous works
results for comparison. Me93 refers to Mellier et al. (1993), Ha97 to
Hammer et al. (1997), Mi95 to Miralda-Escudé (1995) EF99 to Ettori & Fabian (1999)
and Al02 to Allen et al. (2002). When known, the authors' values are
recomputed in our adopted cosmology and with the 1.6 sources redshifts.
For both papers, the center of potential location is assumed to match
the center of cD or is not reported. Me93 core radii have been scaled in
order to take into account the departs between their profile and an exact
softened isothermal sphere. As well, Ha97 find a slope
instead we have only considered models with
(see Eq. (2)). Al02 uses a NFW profile and only gives the scale radius
value but we report on the same line our own measured values for ellipticity
and position angle from Chandra X-ray brightness.
The third column
corresponds either to the scale
radius either to the core radius.
Here, we convert all the position angles in a common definition, which
is clockwise from North to East. The original paper do not report angles in
the same frame but we made the correction except for Ha97 for which we do not know
what is the reference. But in any case, the position angle is so constrained that
these authors must have found a similar orientation as the other ones. Our
definition is more valuable and self-consistent between Chandra, ROSAT,
VLT and HST data.
Models labels with a S refer to purely strong lensing modeling whereas a W stands
for purely weak lensing fits.
The last row (cD+DM) concerns the last family of profiles with a cD and dark
matter halo components and which is simultaneously constrained by strong+weak
lensing. In the first column, we report the permitted inner slope for
generalized NFW profiles (see Sect. 3.4.3).
