PineAPPL interpolation grids, which store theoretical predictions for
high-energy collisions independently from their PDFs and the strong
coupling.
PineAPPL grids are generated by Monte Carlo generators, and the grids in turn can be convolved with PDFs to produce tables and plots, such as the following one:
