[G12] G12 Target Density

[Michael C. Kunkel]

Greetings,

I have finished the G12 target density study. It can be found at
https://clasweb.jlab.org/rungroups/g12/wiki/index.php/G12_Target_Density.

Since the systematic on the density is 0.02%, I am going to side with FX 
and his conclusion that the maximum systematic on the target is due to 
the length on the target and assign a total systematic of 0.5%. This 
0.5% allows for a target length inaccuracy of 40cm +- 0.2cm, which could 
be caused by various system influences.

Thoughts?
