Notes. For all regions, the best-fit values were obtained with the vpshock model. The column density nH,LMC is given in units of 1022 cm-2, the temperature kBTx in keV, the ionisation timescale τ in s cm-3, and the normalization norm in cm-5. The parameter norm is the normalisation of the Xspec model vpshock and is a function of the emission measure. In the last row, the reduced χ2 of the fit is given. The uncertainties given are the upper and lower 90% confidence ranges.
