Hello Origin friends,

I have 6 peaks, A, B, C, D, E, F

I would like to fit them each with a simple Gaussian (for example) in order to obtain the integrated area under the curve.

I would like to do a least squares fit such that:

total area of A + B + C = total area of D + E + F

Is their a way of fitting them all simultaneously to match this constraint?

Very grateful for any advice.

Thanks,
Chloe
