Comparison - Here we compare the parameter fits using D1, and D2. The first plot is the chip-to-chip color term slope relative to the reference chip, indicated by the vertical dot-dashed line, the second is the chip-to-chip color term zeropoint, and the third is the exposure-to-exposure color term zeropoint relative to the first exposure. All y values are in magnitudes.
