Redshift distribution of the galaxies employed in this paper. The y axis is presented on logarithmic scales to enhance the clarity of the data. The black bars depict the redshift distribution of the BGS galaxies, the grey bars delineate the redshift distribution of FP galaxies, and the blue bars illustrate the redshift distribution of TF galaxies. Additionally, the yellow bars represent the redshift distribution of the entire DESI-PV sample, which constitutes a combination of FP and TF galaxies.
