comment Understanding Dirichlet regularization in Sum
So, $S_l = -1/12$? It didn't calculates well: Sum[-(1/12) Binomial[k, l], {l, 1, k}] /. {k -> 3}, am I missing something?

Can you expand a bit more about $S_l$? And that's a binomial coefficient, right?

comment Understanding Dirichlet regularization in Sum
Actually, after this article I tried this. I just can't understand what method Mathematica use; if we add zero, the Maclaurin series shouldn't change, but the answer is different.

Oh, thanks. Didn't thought that the issue is in the (), not primes...

comment Power::infy: error using FindFit
If you want just a rough width of center peak, why not to use something like this: Manipulate[ Show[Rasterize[image], Graphics@{Red, Circle[p, r]}], {{p, {390, 270}}, Locator}, {r, 50, 100}]? It's just allows you to set width and position on eye.

comment Power::infy: error using FindFit
You don't understand what code you run... Can you just describe what you want to get? Width of peak? "Period"? Number of local maximums? I start to think that fitting this (also, this can be really looong... it's a non-linear fit for over 500k points) isn't a good idea.

Can you provide all necessary code? That's not a good idea to people guess and ask what you mean...

And how do you load the image?

First of all, provide the Mathematica code.

comment Trying to solve simultaneous equations based on format found on official website
@DisplayName I just started in assumption that Mathematica is right and tried to prove there is no solution, but when found one - try to find, why Mathematica didn't found any.
