Scatter plots and histograms between two datasets. Each column shows the intercalibration between different channel of AIA and EUI. The solid lines in the scatter plots correspond to the third-order fitting, passing through zero, representing the relationship between FSI and AIA. Here, the x-axis corresponds to the DN/s of FSI observations and the y-axis corresponds to the DN/s of AIA observations. The histograms represent the distribution of differences between the original data and differences after third-order fitting. For both wavelengths, the standard deviations improve after intercalibration.
