From: Spatial uniformity and temporal stability of pixel-to-pixel variation in mini-SiTian CMOS detector
Left panels: as an example, pixel-to-pixel variations of November 2023 for selected regions are composed of \(100 \times 100\) pixels (X from 1900 to 2000 and Y from 1900 to 2000). Right panels: the result of subtracting 17 daily flat field by the November 6, 2023. Color bar is overplotted at the right indicating the normalized electrical signal, respectively. The date and standard deviation are labeled in each panel.
