//   <li> make UV-distance matrix static, to share between multiple instances
//   <li> collect population statistics across all channels
//   <li> 3D bins (ampl-UVdist-channel)?
//   <li> think how to solve "encroaching" problem to achieve a better
//        probability distribution. Perhaps two sets of staggered bins,
//        and for each point use the count of the bigger bin?
