Comparison between the BAGPIPES results for the burst age (left column), burst mass fraction (middle column), and dust attenuation (right column) of seven QPE hosts in common between our sample and the sample in T. Wevers et al. (2024). Top row: comparison between results using different fit instructions in BAGPIPES, where the spectral aperture size is the same. Bottom row: comparison between results using different spectral aperture sizes, where the BAGPIPES fit instructions are the same. Deviations away from the one-to-one line in each plot show whether the difference in results is due to the difference in fit instructions or aperture size. For example, the difference in the burst age in the host of eRO-QPE3 is due to the different fitting method, where using the double power law to model the burst produces an older burst age.
