Distribution of stellar masses for the Q1 dwarf candidates. Top: Stellar mass distribution obtained using the reference SED fitting setup and all available bands for all dwarf galaxies, assuming z = 0.1 (pale blue-violet) and z = 0.05 (dashed blue-violet), as well as for those with spectroscopic redshifts z_spec (opaque blue-violet). Bottom: Only dwarf galaxies with spectroscopic redshifts z_spec, comparing the reference SED fitting results with those obtained using Euclid bands alone (orange). Additionally, it includes results from an alternative SED fitting approach that employs single-burst models with a broader range of metallicities (green).
