Fig. B.1

Photometric uncertainty on the (W1–W2) color as a function of mass at 5 (Left) and 10 Myr (Right), for our sample described in Sect. 3.1. The uncertainties are computed as the quadratic sum of the W1 and W2 magnitude errors, i.e., $σ_{W 1 - W 2} = \sqrt{σ_{W 1}^{2} + σ_{W 2}^{2}}$ ${\sigma _{{\rm{W}}1 - {\rm{W}}2}} = \sqrt {\sigma _{{\rm{W}}1}^2 + \sigma _{{\rm{W}}2}^2}$ . Sources flagged as potentially blended in WISE images (see Sect. 3.1) are shown in orange.
