History: NA software variables

There are really four sorts of variables, which are classified by what the array index means.

Class One:
Array index is the detector. So for example, na.nd.n1.LT4 would be the the left time for detector N1-4.
na.nd.n#.LT?
na.nd.n#.LA?
na.nd.n#.LApedc?

Class Two:
Array index is the hits, lowest index number is hit that hit lowest in the detector. For example, na.nd.n1.hit_tof0 would be the tof? variable for the lowest detector number hit in plane N1.
na.nd.n#.hit_tof?
na.nd.n#.hit_bar?
na.nd.n#.hit_Edep?
na.nd.n#.hit_ypos?
na.nd.n#.hit_xpos?
na.nd.n#.lthit_time?
na.nd.n#.lthit_bar?
na.nd.n#.lahit_Adc?
na.nd.n#.lahit_Adcp?
na.nd.n#.lahit_bar?

Class Three:
Array index is the hits, lowest index number is the hit that had the highest Energy Deposition.

Class Four:
Array index size. This is just a the maximum array size for one of the array variables. For example, for na.nd.n1.lthit_time it would be the largest number of hits in N1 in a given event. These variables are in the form:
Ndata.*
where * is the arrayed variable.
