Comparison between TOPz and GAMA stellar masses for each galaxy. The x-axis shows the GAMA stellar masses acquired using GKV ProFound photometry (see Sect. 3). The y-axis shows the TOPz stellar masses that are computed using the spectral templates from the CIGALE software (see Sect. 2.5). The colour denotes the TOPz photo-z accuracy. The dashed black line is a median stellar mass ratio relation, where M_★,TOPz ≈ 1.3 ⋅ M_★,GAMA. Galaxies where TOPz photo-z are close to the spectroscopic redshiſts follow the stellar masses from the GAMA database very well.
