Detailed Description

RadiusResolutionChebyshev parametrizes the uncertainty on the drift-radius as a function of the drift radius itself and not of the drift time.

It has a pointer to the corresponding rt-relation which is used to translate the drift time into a radius before parsed through the parametrized chebyChev polynomial
