From: Spatial uniformity and temporal stability of pixel-to-pixel variation in mini-SiTian CMOS detector

Values of nine randomly selected pixels vary over time (i.e. daily pixel-to-pixel variations; blue dots). The results of the monthly pixel-to-pixel variations overplotted with red asterisks. The black and green lines represent the median values and the standard deviation, respectively. The standard deviation is labeled in each panel.
