Detailed Description

The Formula used is the highland formula for the projected scattering angle :

\( \theta_{ms} = \frac{13.6MeV}{p}\cdot\sqrt{t/X_{0}}[1 + 0.038\ln(t/X_{0})] \)

What is returned is the square of the expectation value of the deflection \( < (\theta_ms)^2 > = \sigma_ms^2 \)

For electrons the

virtual StatusCode AthCommonDataStore< AthCommonMsg< AlgTool > >::sysStart ( )

overridevirtualinherited

Handle START transition.

We override this in order to make sure that conditions handle keys can cache a pointer to the conditions container.
