Difference in photo-z for galaxies from COSMOS2020 re-fitted with LePHARE using just the DAWN PL bands compared to the original COSMOS2020 (Weaver et al. 2022) values. The redshift range 1.3 ≤ z ≤ 2.5 shows greater spread with a tendency towards higher redshifts, especially in the wings, due to lack of constraint on both the Lyman break and Balmer break. Galaxies outside this interval do not have the same problem and constrain at least one of the two breaks. A small number of galaxies scattering to higher redshifts can affect the observed galaxy SMF in this redshift interval.
