History: NA software variables

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

Array index is the detector. So for example, na.nd.n1.LT element 4 would be the the left time for detector N1-4.

Class One Software Variables

Variable Name	Description
na.nd.n1.LT	This is the Left Time Neutron Plane 1, corrected for all corrections in the DB used to create it.
na.nd.n2.RT	This is the Right Time. See Left Time description. For all variables that might have a left or right, L refers to left and R refers to right (of this variable type).
na.nd.m1.LA	This is the Left raw Adc value for the Marker Bar.
na.nd.s1.RApedc	This is the Right pedestial corrected Adc value for the Sums.

Array index is the hits, lowest index number is hit that hit lowest in the detector. For example, na.nd.n1.hit_tof element 0 would be the tof? variable for the lowest detector number hit in plane N1.

Class Two Software Variables

Variable Name	Description
na.nd.n4.hit_tof	This will be the time of flight variable. Currently it is the Average Time? for a given hit in Neutron Plane 4.
na.nd.n3.hit_bar	This is the variable that gives the bar number for a given hit in Neutron Plane 3.
na.nd.n7.hit_Edep	This is the variable that gives the energy deposited in a bar for a given hit in Neutron Plane 7.
na.nd.n6.hit_ypos	This is the variable that gives the Y Position? for a given hit in Neutron Plane 6.
na.nd.n5.hit_xpos	This is the variable that gives the X Position? for a given hit in Neutron Plane 5.
na.nd.n3.lthit_time	This is the variable that gives the corrected time for a left tdc hit.
na.nd.n3.lthit_bar	This is the variable that gives the associated bar number with a left tdc hit.
na.nd.n1.rahit_Adc	This is the variable that gives the raw Adc value for a right adc hit.
na.nd.n1.rahit_Adcp	This is the variable that gives the pedestal corrected Adc value for a right adc hit.
na.nd.n1.rahit_bar	This is the variable that gives the associated bar number with a right adc hit.

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.
