Notes. All uncertainties are at the 1σ level.
Surface area of the ellipsoidal region, for which we assumed a radius equal to b for the third dimension (i.e. a prolate spheroid).
Average distance from the centre of the region to the average between the centre of the bubble and the position of the ULX. For the bubble we quote instead the semi-major and semi-minor axes.
Integrated extinction-corrected luminosity in the region. The error is propagated from the error flux map and takes into account the uncertainty on E(B − V). We assumed a distance to NGC 1313 X–1 of 4.25 Mpc in the calculations of the luminosities.
Mean and standard deviation of E(B − V) in each region to provide some reference values, although the extinction correction was applied on a pixel-by-pixel basis.
Shock velocity estimated from the observed line ratios in each region after comparison with the MAPPINGS libraries (see text for details).
Estimated explosion energy in the case of an evolved SNR in the pressure-driven snowplough phase (see Sect. 4.2 for details).
