Table 2: Fluxes for the strong emission lines in units of 10-16 erg s-1 cm-2 corrected for Galactic extinction. The magnitudes are given in AB units. The first three rows correspond to different aperture sizes. For the WR and SN region the radial apertures are 2 $^{\prime \prime }$ defined to include all the flux from the regions seen in the H$\alpha $ image. Below the first three rows the fluxes are extracted from the images in a square aperture of $3\times 3$ spaxels equivalent to 4 arcsec2 around the coordinates in Col. 1. The magnitudes are calculated from the spectra extracted within this aperture. Note that the properties vary with the chosen aperture; especially the equivalent widths show differences as described in Sect. 3.4. The oxygen abundance and N/O abundance ratio in the two last columns are discussed in Sect. 3.8. The uncertainties for line fluxes and magnitudes are $\approx $10%, <4% for the H$\alpha $ and H$\beta $ EW, 0.12 mag for the reddening, and 0.14 dex for the oxygen abundance calibration. The uncertainty of the N/O ratio is 0.2 dex. The last row gives the mean of the individual regions, and the uncertainty is the standard deviation.
