perfect many thanks. Those of PDF4LHC21_nnlo_mc_5.txt are the ones you produced already right?

Yes! These are exactly the same.

Hi @juanrojochacon, last week in the PDF4LHC21 meeting, it was suggested to superimpose in Fig. 5.12 the distribution from META40 with positive definite PDFs (this seems to be a sensible suggestion). I am attaching below the predictions per replica and per bin (similar to the above). With the script that you have, could you perhaps add these results to the histogram plots? Or else, please let me know if you want me to take care of this.

BIN Pred/replica
0 PDF4LHC21_40_0.txt
1 PDF4LHC21_40_1.txt
2 PDF4LHC21_40_2.txt
3 PDF4LHC21_40_3.txt
4 PDF4LHC21_40_4.txt
5 PDF4LHC21_40_5.txt

This is easy enough, I can try to do it. I am not sure it will look pretty but we can try.

However @Radonirinaunimi I don't need all this info: at the end of the day the Hessian 40 set leads to a gaussian distribution right?

So if you can process these numbers to get the central value (prediction from central pdf set) and the standard deviation I can then just superimpose a gaussian to the predictions from the prior, right?

Thanks!

Yes, this is correct! I'll compute the means and STDs and will post them here.

ok good this saves a bit of time for me then

Got them. This is the script I used:

https://www.dropbox.com/s/cjonu7tl9i44xuu/negative_xsecs.tgz?dl=0

Would you mind adding the pdf4lhc21_40 gaussian distributions yourself? I am a bit swamped with tesching.

Thanks, Juan

Sure! I can do that!
