Stellar and disk properties of the sample. Left: median fraction of systems, NIR and FIR excess (fraction of stellar flux), mass accretion rate (log(M_⊙ yr⁻¹)), stellar variability (mag), and integrated millimeter flux at a same distance (mJy) for the subsamples of Table 1. The median value of the entire sample is at the center of the respective column while the neighboring vertical lines indicate the 30th and 70th percentiles (for quantities of individual sources only). Remarkable values (smaller and larger percentiles or clear outliers) that are discussed in the text are highlighted by a circle. Right: FIR vs. NIR excess diagram of all sources. The median values of the entire sample determines the four quadrants. The diamonds indicate the median values of Taurus (red), Upper Sco (blue), Orion (cyan), Chamaeleon (green), Lupus (gray), Corona Australis (violet), and η Cha (orange). The vertical bars illustrate the relative number of sources from all regions in each quadrant.
