Query: Cosmological constraints from the convergence 1-point probability
  distribution   We examine the cosmological information available from the 1-point
probability distribution (PDF) of the weak-lensing convergence field, utilizing
fast L-PICOLA simulations and a Fisher analysis. We find competitive
constraints in the $\Omega_m$-$\sigma_8$ plane from the convergence PDF with
$188\ arcmin^2$ pixels compared to the cosmic shear power spectrum with an
equivalent number of modes ($\ell < 886$). The convergence PDF also partially
breaks the degeneracy cosmic shear exhibits in that parameter space. A joint
analysis of the convergence PDF and shear 2-point function also reduces the
impact of shape measurement systematics, to which the PDF is less susceptible,
and improves the total figure of merit by a factor of $2-3$, depending on the
level of systematics. Finally, we present a correction factor necessary for
calculating the unbiased Fisher information from finite differences using a
limited number of cosmological simulations.
