1. Hall A 11 GeV Arc Energy Mapping

2. Mapper in shed 9 1234 = “fixed” NMR to measure B 0 Mapper measures ∫Bdl and B 0 In this configuration the mapper and “fixed” NMR are cross calibrated Step 1

3. Mapper in shed 9 1 234 Step 2 ∫Bdl 1 vs. B 09

4. Mapper in shed 9 2 134 Step 3 ∫Bdl 2 vs. B 09

5. Mapper in shed 9 3 124 Step 4 ∫Bdl 3 vs. B 09

6. Etc.

7. Mapper in shed 9 8 123 Step 9 ∫Bdl 8 vs. B 09

8. Mapper in shed 4 9 123 Step 10 (repeat step 1)

9. ∫Bdl i vs. B 09 i=1,2,3…8 In the end we have:
