W values and Fano factors
- Implement default values for W and F for all available gases.
- By default,
TrackSrim
andTrackTrim
now use the W value and Fano factor provided by theMedium
. The possibility to set W and F explicitly inTrackSrim
andTrackTrim
is kept for backwards compatibility for the time being. - By default,
TrackSrim
now retrieves the atomic number of the target and the number density from theMedium
(i. e. the effective A and Z of the target do not need to be set explicitly by the user although this is still possible).
