Notes. Average phase-reddening coefficients and zero-phase NIR/BLU spectral slopes for selected ROIs from 1000 bootstrap iterations. The errors are the 1σ standard deviations. The Desc. column provides a synthetic description of the ROI (see Sect. 2 for details). RU (BU) stands for Red (Blue) unit.
