Fig. 2


Metallicity measurements (solid circles), metallicity estimates (open circles), and gradient estimate (solid red line) for NGC 5806 compared to the spiral-galaxy sample (gray dashed lines) by Gusev et al. (2012). The dashed blue line shows a first-order polynomial fit which includes the central oxygen metallicity measured for NGC 5806 using an SDSS spectrum, and the dashed red line shows the same fit with the metallicity datapoint at the center of the galaxy excluded.
