Poisson background subtraction

Optimize signal and background counting times for a background-subtracted neutron scattering measurement, assuming independent Poisson uncertainty in both channels.

Measurement inputs

The optimized time split minimizes the uncertainty of the subtracted rate signal - background for a fixed total counting time.
