Change matching grids Q2min #42

Closed Radonirinaunimi closed 2 years ago

Radonirinaunimi commented 2 years ago

Changes the kinematic grids used to generate the Yadism matching data.

Radonirinaunimi commented 2 years ago

@giacomomagni I think that we can try with this as a start. The real datapoints will then be cut off at $QI^2 = 28~\rm{GeV}^2$ from which the matching grids will start. For $Q{II}^2$, Juan suggested to take at least $Q{II}^2 = 900~\rm{GeV}^2$, however, I think we should check first if the smaller values of $Q{II}^2$ we could fit both w/ and w/o input scaling. Also, given that some of the real datapoints will be removed (for NUTEV about 500 will be cut off) I refined a bit the grids.

@giacomomagni, could you please generate the new grids with the latest commit. So basically the points are now different for each experiment and they correspond exactly to the $x$-points in the dataset. While doing so, could you also double check if something has been broken?

giacomomagni commented 2 years ago

Okay @Radonirinaunimi. I'll update the grids.

Radonirinaunimi commented 2 years ago

The kinematics per experiments are now fixed, some notes for future reference:

The only files that have changed are the kinematics and the coefficients
Some of the matching files (saved as numpy arrays) have also been changed (while they shouldn't). However, these were carefully checked and attributed to numerical errors.

This should be merged now and once https://github.com/NNPDF/nnusf/pull/41 is also merged (which I'll do in a while) then we can run the long-awaited fits.
