Ana: Discussion on the calculations with AS1063 and new cosmological
constraints.

Recovers the results from Caminha et al. 2016 with the same images, but
get a biased result and RMS=1.5" when including all the images. There is
still a bias with the new images from Karman et al. 2015.

News on papers:

Coleman et al, 2016, The
Mass Distribution of the Unusual Merging Cluster Abell 2146 from Strong
Lensing, 1609.06765v1

The fact that the X-ray appears ahead of the BCG-A could be a projection
effect. The study requires spectroscopic data to conclude.

Cassano et al., 2016,
Can giant radio halos probe the merging rate of galaxy clusters?

The fraction of giant radio halos and to the fraction of merging
clusters gives insights into the duration of merger-induced disturbance
\tau_m, and the typical merger mass ratio \xi_m.

Martizzi & Agrusa,
2016, Mass modeling
of galaxy clusters: quantifying hydrostatic bias and contribution from
non-thermal pressure, 1608.04388

This is another model to describe the bias between X-ray and mass. TODO:
check which model is actually used in cosmological analysis, such as
Planck.
