Notes. The total galaxy stellar masses derived from our STARLIGHT fits and by Neill et al. (2009) are also given.

^(a)

S/N of the total galaxy spectra.

^(b)

Values at the SN radial distance interpolated from the radial dependencies derived from the azimuthally averaged spectra (Fig. 14).

^(c)

S/N of the azimuthally averaged spectrum that is closest to the radial distance on the SN.
