why do you get the range after the fit?

[kjappelbaum]

maybe i'm to tired, but i do not get the logic here https://github.com/gSulpizio/isotherm-analysis/blob/1013b45d10287ad30288894708536716ff55f85d/src/BETFitLinearDouble.ts#L26-L32

So here the idea was to tackle the noise handling problem in a different manner: if we fit the BET equation first to the data, we can then get a linear fit on the fitted function instead of the real data?

[kjappelbaum]

yes, the issue was that i did not see the second fit

Do you see a mistake somewhere? I also still wonder what N represents here because I get a negaqtive small number for it which makes me suspicious
