For an LSST-like survey, four-bin tomographic weak lensing peak counts shrink the Omega_m-sigma_8 error contour by about a factor of five relative to 2D peak counts, and can simultaneously constrain photo-z bias to 10% and scatter to 5%.

Cosmological studies from tomographic weak lensing peak abundances and impacts of photo-z errors
For an LSST-like survey, four-bin tomographic weak lensing peak counts shrink the Omega_m-sigma_8 error contour by about a factor of five relative to 2D peak counts, and can simultaneously constrain photo-z bias to 10% and scatter to 5%.
