w-correlation matrices from SSA decomposition of S5 1044+71 LC. Dashed red lines separate the top-left region, containing the trend and periodic components, from the rest of the matrix, where noise components are more dominant. (Left panel) General w-correlation matrix, where each point $\left({\tilde{Y}}_N^{(i)},{\tilde{Y}}_N^{(j)}\right)$ represents the correlation between the i-th and j-th component. The color scale indicates the strength of the correlation, with yellow representing high correlation and dark purple representing low correlation. The diagonal represents self-correlation. (Right panel) Zoomed-in view focusing on the first 10 components, providing a detailed examination of the correlations between the initial components that typically capture key trends and periodic signals.
