All Tables

Table 1: The adopted and derived parameters of the radial oxygen abundance distributions in galaxies.
Table 3: The derived parameters of the radial distributions of the nitrogen abundance and nitrogen-to-oxygen abundance ratios for our sample of galaxies.
Table 4: Galaxies with the observed H II regions which are expected to not belong to the upper branch of the $R_{\rm 23}- {\rm O/H}$ diagram and the radius R^* where the oxygen abundance decreases to around $12 + \log~($ O/H) = 8.2.
Table 5: The characteristic oxygen abundance (at $r=0.4R_{\rm 25}$ ), gas (atomic and molecular) mass fraction $\mu$ , atomic and molecular hydrogen contents, and rotation velocity for spiral galaxies from our sample. The oxygen abundance is given as 12+log (O/H).
