Average magnitude of 541 vectors (default Hm) = 15148.27366

Expected norm of local field vector Hm? (0 for default above) 1000

Combined bias vector B:
 9955.15 -7948.26  8511.80

Correction matrix Ainv, using Hm=1000.000000:
  0.25060   0.02942  -0.02955
  0.02942   0.31692   0.00789
 -0.02955   0.00789   0.30592

Where Hcalc = Ainv*(H-B)
