Individual and global trends of MAH in bulges and discs. Left and centre columns: individual MAHs of spirals separated by increasing T-Types (from top to bottom). In each panel, the mean-stacked MAH for high-mass components (M > 10¹⁰ M_⊙) are shown as thick black dot-dashed curves, and low-mass components (M < 10¹⁰ M_⊙) as thick black dashed curves. These are depicted as red dot-dashed and dashed curves respectively for the Sa type (row 1), which also serves as a reference for all following types for easier visual comparison. Right-most column: bulge and disc masses in red and blue, respectively, with their median masses shown by dotted lines.
