Calculation Questions! #138

I buy a NanoVNA kit from China , I think your project is wonderful . I find your open source and I analyzed your code , but still have some questions . I cant understand why you calculate Es = (S11mo'/s11ao + S11ms’)/(S11mo' - S11ms’) uses s11ao , in theory , Es = (S11mo' + S11ms’)/(S11mo' - S11ms’) . And when you calculate this , why you did not divide s11ao , I think it increase the number of Es , but S11 you calculate is still right . It confuse me a lot . So can you tell me how to understand this? Thank you very much!
