Notes. All the reported values are in units of magnitudes. col₀ is the reddening-corrected median colour of the RGB tip. The colour for the RGB tip in Euclid-VIS I_E is JKC V-I; The uncertainties on $M_{mag}^{TRGB}$ $M_{\mathrm{mag}}^{\mathrm{TRGB}}$ have been computed summing in quadrature the global uncertainty on the distance modulus, the largest between the −1σ and +1σ uncertainty on mag₀^TRGB from Table 1, and the adopted uncertainty in the photometric zero point. The value within parentheses is the uncertainty when the latter factor is neglected.
