The gridding code (spec_driver_fits) implements a classic method of gridding, by picking a convolution kernel, and weighing samples by their emprically determined RMS.

Another approach is to study kriging (e.g. https://en.wikipedia.org/wiki/Kriging) if that's going to help us. A recent JOSS paper by Molinsky on Pyinterpolate made me aware of this approach.
