1 added + 1 modified, total 2 files
Adding a derivation of the unit conversion factor in pdf and referencing it in the javadoc.
The derivation is slightly confusing due to
a) the fact that I originally thought the value would be the reciprocal.
b) Minor notational clumsiness
However, it clearly establishes the numerical value that is to be used throughout org.lcsim.
