Fig. 4


Spectral energy distribution (SED) of the ULX (upper section) and nearby (lower section) blobs from broadband photometric data (black squares) and their best fit population synthesis models (thin lines). In both panels, the dotted line shows the fit with solar metallicity value Z, while the solid line shows the fit with metallicity 0.4 Z. The contribution from major emission lines was subtracted from the photometric data. Error bars are about of the size of the symbols.
