Two examples of light curves (top panels) and spectra (bottom panels) for two sources contained in the eRASS1 Main catalogue, generated from the released source products. On the left hand side, we show the light curve and spectrum of the first eROSITA Quasi Periodic Eruptor (eRO-QPE1; Arcodia et al. 2021; 1eRASS J023147.1–102011; DETUID: eb01_038099_020_ML00005_002_c010). The light curve (top left) is binned in individual eroday visits, separated by 4-hours intervals. The spectrum (bottom left) is taken from all data, and fitted with an absorbed black body (zbbody). On the right hand side, we show one of the brightest AGN in the SEP region (1eRASS J061148.2–662434; DETUID: em01_093156_020_ML00001_012_c010; Bogensberger et al. 2024). Given the high ecliptic latitude, the source is visited over two separate long periods of about 14 and 24 days, respectively. The light curve (top right) shown has the original binning in 10 seconds intervals. The spectrum (bottom right) is fitted with an absorbed power law. Note that both best-fit lines (light blue) are simple physical models aiming to guide the eye and do not intend to encompass all the potential detailed features present in the spectra. The background model is shown as black dotted lines in both figures. For more details on eROSITA spectral modelling and appropriate handling of background spectra, refer to Sect. 3 of Liu et al. (2022b).
