Could you propose some standard method to do this?
In the meantime, we have to live with RGB magnitude.as estimated earlier (hopefully, there will be more measurement results tonight  |
If you have a raw image, open it in Iris. Using the "Digital Photo" tab decode the raw file as normal. There is a RGB separation button. This will then create 3 files, one for each colour. You then analyse the green channel.
