inlinevirtual

Process one hit, and optionally it's corresponding kinematics track. Users should over this to process each hit.

Parameters

h	Hit
p	Associated track

Returns: false on error

inline

Scale a graph by density (multiply) and mass (divide).

Parameters

graph	Graph to scale
density	If `true`, scale by the Si density ($=2.33$/cm^3$). The y axis is assumed to have units of $MeVg^{-1}cm^2$.
mass	Mass to scale with. The x axis is assumed to be the kinetic energy of the particles in units of $GeV$.
