Notes. Column (1) gives the name of the galaxy; Cols. (2)−(5) show the gradients of mean ages divided into light-weighted (LW) and mass-weighted (MW) values, as well as into the gradients along the bar major axis (MA) and the minor axis (MI); Cols. (6)−(10) show the gradients of mean metallicities in the same format as for the ages. The last row shows the mean values for all galaxies and the standard deviation between individual objects. The standard deviation of the mean is larger than the propagated error of the individual objects. ( ⋆ )NGC 5248 is a clear outlier in this and following analyses and not included in the calculation of the means.
