Query: Shape Profiles and Orientation Bias for Weak and Strong Lensing Cluster
  Halos   We study the intrinsic shape and alignment of isodensities of galaxy cluster
halos extracted from the MultiDark MDR1 cosmological simulation. We find that
the simulated halos, are extremely prolate on small scales, and increasingly
spherical on larger ones. Due to this trend, analytical projection along the
line of sight produces an overestimate of the concentration index as a
decreasing function of radius, which we quantify by using both the intrinsic
distribution of 3D concentrations ($c_{200}$) and isodensity shape on weak and
strong lensing scales. We find this difference to be $\sim 18\%$ ($\sim 9\%$)
for low (medium) mass cluster halos with intrinsically low concentrations
($c_{200}=1-3$), while we find virtually no difference for halos with
intrinsically high concentrations. Isodensities are found to be fairly
well-aligned throughout the entirety of the radial scale of each halo
population. However, major axes of individual halos have been found to deviate
by as much as $\sim 30^{\circ}$. We also present a value-added catalog of our
analysis results, which we have made publicly available to download.
