How can I fit multiple curve to one curve?

Hello!

I have a curve wich is the result of an experiment. Now I need to find some curves that will be superimposed and make this curve . I have attached a picture. Actually I have the dark curve and I need the red curves (I have their general mathemtical formulation but I need to tune some parameters). Could you please help me with this problem?

Regards,
