Types of variables
Acd*Count*, Acd*No* Number of hits of a particular type
Acd*ActiveDist3D, Acd*AcdDist "Active Distances", signed measure of track extrapolation to hit Acd dectector element
> 0 means that track extrapolates into hit element, < 0 means that track extrapolates outside hit element.
Acd*ArcLen "Arc Length", distance along track where active distances value is calculated. This is also a signed value,
> 0 means along upward going branch of track, < 0 means along downward going branch of track. (or at least below the
head of the track).
Acd*Err "Error", proejected error on track extrapolation. This variable is not being filled correctly yet.
Acd*_Down: Down going version of variables, calculated for downward branches of tracks.
AcdTkr1*: Variables calculated only for best track
AcdVertex*: Variables calculated for event vertex
Acd*Ribbon*: Variables calculated with respect to ribbons. Most of the variables are with respect to the tiles only.
Acd*Energy*: Energy deposited in a tile or ribbon, expressed in MeV, calculated using MIP equivalent. For tiles we report the greater of the two pmt values. For ribbons we report both values seperately.
Acd*RibbonLen*: Length along ribbon where value is reported. 0 is center of ribbon, > 0 means towards +x or +y side, < 0 means
towards -x or -y side.
