Slice through the UCHUU-DESI catalogues with objects coloured by tracer type: BGS (blue), LRG (green), ELG (orange), and QSO (red). The slice shows an 80 deg wedge projected into comoving coordinates using a Planck background cosmology, extending out to a maximum redshift of 2. The projected thickness is 1 deg for QSOs and 0.5 deg for ELGs. The thickness for the BGS and LRG samples is adjusted with redshift to achieve a constant average projected number density. The transparency of points out of the projection plane falls off with Gaussian weighting.
