Fig. 5


Diagnostic log([OIII]/Hβ) vs. log([SII]/Hα) (left), log([OIII]/Hβ) vs. log([OI]/Hα) (middle), and log([OIII]/Hβ) vs. log([OIII]/[OII]) (right) diagrams. In the left and middle diagrams, the boundary lines were taken from Kewley et al. (2006), while in the right diagram the boundary line was taken from Evans & Dopita (1985). The ULX blob is represented with a red cross, while the nearby blob is shown with a blue star. The B symbol indicates the line ratios computed from R500B grism, while the R shows the line ratios computed from R500R grism. Statistical errors are smaller than the symbol sizes, except those for log([OI]/Hα).
