Member Function Documentation

addMCSEffect()

void o2::track::TrackParCovFwd::addMCSEffect

(

double

x2X0

)

Add multiple Coulomb scattering effects to the track covariances. Only angular and pt MCS effects are evaluated.

• x_over_X0 is the fraction of the radiation lenght (x/X0).
• No energy loss correction.
