As a check that these results are sensible, a sample
of size 
was collected using spacing 200.
This sample gave an estimate 
with MCSE
(0.0015, 0.00029)
The final estimate of the inverse Fisher information is
If we this `final estimate' to be the truth, our earlier estimate had actual error (0.017, -0.0032) which is about the same size as its stated MCSE (0.019, 0.0037). The MCSE calculation seems to have worked.
