The ratios are established, one using established by the specks of the pilter and by the specking of the c c d detector. And for some systems, it's a one to one to two. Others it's a point five to one. It all depends on the quantum efficiency, a distribution of the of the censer. You know, is it more sensitive in the green than the blue or the red? So those the proportions are established from the detector and the pilters,. Then you need then putting it together is kind of straightforward.
