Columns 3 and 5: the linear regression constant of the fitting
that represents the Lick index at one effective radius. For Fe5270, Na D, Mg1 and Mg2, the third line shows their gradients measured in NGC 1052 by Carollo et al. (1993). For Mg2 only, the fourth and fifth lines show the gradients measured respectively along the major and minor axis of NGC 1052 by Couture & Hardy (1988). |
