Further to my query. In AIP4WIN Bayer conversion settings, DeBayer, Convert Colour to Grayscale I set Red Scale=Blue Scale =0 and Green Scale =1, opened a RAW camera image and saved it as FITS. Using Measure/Statistics the max value = 15305. 

I then set Red=Blue=Green=1 and opened and saved an image as above. The max value was then given as 45915 which is 3x the 15305 obtained previously (A calibrated image has a max value of 40471.8).
Are the red, green and blue channels being added?
