Best-fit spectra for six selected sky tiles within 220◦ < l < 235◦, within the dashed black lines shown in Fig. 1. The left column shows spectra within the northern hemisphere at decreasing latitudes. The right column shows spectra at similar latitudes in the southern hemisphere. The black data show the eROSITA spectrum, while the grey points show the flux measured by ROSAT in the softest bands. The solid lines show the contribution from the local hot bubble (red), the warm-hot bubble (blue), the 0.7 keV component (green), the cosmic X-ray background (CXB; magenta), and the instrumental background (black). The inset reports the Galactic latitude and longitude of the centre of the sky tile as well as the total hydrogen column density of neutral absorption derived from the HI4PI survey N_H,HI4 and the best-fit value, N_H,bf. The dotted lines show the contribution of the various components of the instrumental background. The lower panels show the fit residuals, with the sky tile number and reduced χ².
