!!!+Neutron detector database (by Jon Miller)

+ ^
The neutron arm database is a database of scintillators. In the database there are tags which tell the analyzer where to find the information. In later databases there are 11 sections: 7 for the neutron planes, 2 for the veto planes, 1 for the neutron sums and 1 for the marking signals. These are all laid out in the global section, which is denoted by the tags:
[[ na.global ] and [[ na.global.done ]
Here the values are a calib for gain, pedestal, resolution (multiplicative factor), time offsets (toff), time walk (walk), low tdc limit (for example llowtdclim), up tdc limit(for example luptdclim), and wrap point (for example lwrapa). This can be repeated for a different sort of detector. For example, the next line for plane 7 of the neutron arm is
40 44
