Columns. (1) Target name; (2) source type; (3) number of spectra available; (4) number of reconstructed components; (5) fractional variability and its uncertainty; (6) percentage of explained variance; (7–10) percentage of variance explained by each component; (11–14) spectral index of the n component; (15) long-term colour trends. When more than one trend is reported, it goes from lower to higher flux states.
