Detailed Description

Spin precession class. Wrapper for an R(t) TF1, but taking relevant parameters such as g factor, magnetic field strength, and detector angle.

The SpinPrec class. Construct with

GamR::AngDist::SpinPrec prec(gfac, amp, theta, B, timestart, timedir);

GamR::AngDist::SpinPrec

Definition TDPAD.hh:33

and get the relevant TF1 (to fit) with

prec.GetFunc();

Only the g factor and amplitude will be free parameters in the fit. Use setting functions to change the parameters and/or starting guesses. Note that GetFunc() returns a clone of the TF1 stored in the class - this way the parameters can only be editted through the appropriate setters.
