Figure caption: The charge a pixel collects in a certain ROI depends both on its gain and on its relative position inside the ROI (yellow rectangle). In all three cases the ROI has size 22 × 26 (the most abundant size), and is the average of a different number of events (#events) of the same size and at the same position.

Figure caption: Example of different ROIs in different positions and their mean (central plot). The tracks shown are from photons at 3.69 keV. We do the averaging both to ROIs of the same shape and at the same position (to obtain average ROIs), and also to ROIs of the same shape but at different positions (to obtain the reference ROI for that shape).

Figure caption: Same as Figure 8 right, but for different pixels. The variations are significant, even if the pixels are contiguous.

Figure caption: Energy resolution, as a function of energy, in a 1.5 mm radius spot at the center of the three detectors onboard IXPE, computed without and with the application of pixel equalization.

Figure caption: Slope and offset terms of the relation between PHA and PI energy channels, generated starting from nonequalized and equalized data, in 100 × 100 spatial bins, for the IXPE detector 2. After equalization, large-scale variations are much less evident; remaining effects are eventually corrected with another calibration procedure. The tracks visible in the offset maps, instead, are due to alpha particles produced by residual radioactivity of the Beryllium window. In fact, the large energy deposit they release reduces temporarily the gain of the GEM in the region which is involved in the multiplication (Baldini et al. 2021).

Figure caption: Spurious modulation as a function of energy for the three detectors flying onboard IXPE. Some improvement is present when applying pixel equalization at low energy in detector 2 and 3; no improvement is visible for detector 1 for which spurious modulation is already very low.
