Using lognormal simulations, the authors find that BINGO 21 cm intensity mapping cross-correlated with LSST photometric galaxies can detect the HI signal even with photo-z errors, though with significance comparable to autocorrelation.

Detectability of the 21 cm signal with BINGO through cross-correlation with photometric surveys
Using lognormal simulations, the authors find that BINGO 21 cm intensity mapping cross-correlated with LSST photometric galaxies can detect the HI signal even with photo-z errors, though with significance comparable to autocorrelation.
