PCA decomposition for the Y- (top row), J- (middle row), and H-band (bottom row) light curves. Color-coded are the contributions of each of the coefficients with a 2σ range: p₀ (left column), p₁ (middle column), and p₂ (right column). The sample mean is shown as a solid red line. The values in parentheses are the percentages of the explained variance. Three components explain ∼90% of the variance for each of the bands.
