Radial oxygen abundance distribution in NGC 1058. Panel a: Oxygen abundances based on the slit spectra of H II regions. The squares denote the abundances estimated through the R calibration for individual measurements, the circles designate the (O/H)_S abundances. The crosses mark the median values of the slit spectra-based abundances in bins of 0.1 in the fractional radius determined using both the (O/H)_R and the (O/H)_S abundances for individual H II regions together. The bar shows the scatter in each bin. Panel b: Grey points denote the (O/H)_S, IFU abundances based on the extracted IFU (CALIFA) spectra of individual H II regions. The dark circles mark the median values in bins, and bar shows the scatter in each bin. The crosses mark the median values of the slit spectra-based abundances and come from panel (a). Panel c: Same as panel (b) but for the (O/H)_R, IFU abundances.
