    Using Set Calibration my master flats are dark and bias subtracted (ADU values 25K - 30K) but not normalized where the ADU pixel values are 1.0 +/- 0.x). The Flat Norm selection is monochrome. Can normalized Flats be created with Maxim?

    The masters are saved bias and flat calibrated, but otherwise unmodified. This allows them to be easily reloaded into the calibration tool later, i.e. there is absolutely no difference in handling between raw flats and master flats.

    When you load a flat group to perform a calibration, they are normalized (and 1/x applied) at that time, in memory.
