Simultaneous spectral fit of eRASSU J052914.9−662446 using eROSITA spectra of the different epochs defined in Table 1, namely epoch 1 (black), epoch 2 (red), epoch 3 (green), epoch 4 (blue), and epoch 5 (turquoise), together with the best-fit model as histograms. The spectrum for each eRASS is extracted by combining data from the TMs with the on-chip filter. The residuals are plotted in the lower panels.
