Comparison - Here we compare the parameter fits using RAW, TWILIGHT FLATTENED, and FULLY PROCESSED images. The first plot is the chip-to-chip zeropoint relative to the reference chip, indicated by the vertical dot-dashed line, and the second is the exposure-to-exposure zeropoint relative to the first exposure. All y values are in magnitudes.
