Notes. Slopes of the linear fits to the stellar population properties along the inner bar major (MA) and minor axis (MI) in the radial range of the inner bar (in units of Gyr arcsec−1 and dex arcsec−1). We further provide the mean stellar population properties in this radial range (in units of Gyr and dex).
