Log:
Corrected an error in the definition of eta.
This difference arises from a different definition of the constant c...
Basically, this only affects
the obtained F_eta value by dividing it by a factor of sqrt(3) independent of
the magnetic field.
Hence, consitency evaluation was fine before this correction, except that
values were multiplied by
sqrt(3).
Also, the test-suite values for F_eta were changed so the test still passes.
These changes follow a thread started at:
