A null test of BNT-transformed cosmic shear cross-spectra can constrain Omega_m and w0 geometrically, but requires photometric redshifts known to about 10^-3 and is subdominant to standard 3x2pt analysis.

Cosmic shear nulling as a geometrical cosmological probe: Methodology and sensitivity to cosmological parameters and systematics
A null test of BNT-transformed cosmic shear cross-spectra can constrain Omega_m and w0 geometrically, but requires photometric redshifts known to about 10^-3 and is subdominant to standard 3x2pt analysis.
