A logarithm against a power, over a hundred and twenty-eight decades

A logarithm against a power, over a hundred and twenty-eight decades
A logarithm against a power, over a hundred and twenty-eight decades. The canonical logarithmic correction 1/ln(1/eps) against the square root of eps, on the same axes. The power law is at 10⁻⁶⁴ after a hundred and twenty-eight decades; the logarithm is still at 0.0034, which is a third of a per cent and is the correction, not the answer.

3 essays call regime-exact. The drawing above is what it returns with no arguments at all; every call below passes it something, because a placement that passes nothing draws whichever member of the family the generator happens to default to rather than the one its essay argues about.

It is also the blast radius. Changing regime-exact changes every figure listed here at once, and on this site it may change what they assert as well as what they show — which is what has to be rebuilt and looked at before the change is believed.

Where it is called

What each of these essays asks for instead of the defaults is on the regime index, which reads the parameters back out of the finished figures rather than out of the placements.
