Can I ask one question about fitting?
I want to fit rotated hyperbolic pattern.
With unrotated hyperbolic pattern I just used TF1 and function which returns
par*sqrt(1 + pow(x/par,2));
However when the pattern is rotated of course I can’t simply use this function.
New function with rotation includes y^2, x^2, xy terms.
Is there any way to fit ‘rotated hyperbola’?
I tried to rotate this ‘rotated pattern’ again to make it looks like ‘unrotated pattern’ and fitted with simple function.
However then I don’t know how much should I rotate… I just decided the angle of rotation by my eyes.
I want to parameterize this angle too…
Thank you so much to think about it together!
