updating 2018 GTs from PPD latest recommendations

[panwarlsweet]

Dear Simone,

I am making this PR to update the 2018 GTs according to the latest PPD recommendation. But before you merge I need to clear a few points.

1. For 2018 Data, GTs work perfectly.
2. For 2018 MC, the v20 2018 shows the error [1] when I try to run on 2018 mircoAODs so, for now, I have kept it v19 (from link [2], it shows that only uncertainty changes between v19 and v20 mc tag, central values are same).

The problem with v20 also was reported at [3] in December so I preferred to stick with v19. If you find that v19 is good then GTs are correct but if we need to go with v20 then could you please help me fix the error?

Thanks,
Lata

Hello @panwarlsweet, we will keep v19 for the moment. Have you tried to follow the instructions you can find in the twiki liked to the HN thread you mentioned?

Best,

Hello @simonepigazzini

I read all the HN posts related to this and when I read the comment at [1], it says that it should work for all the release afterward CMSSW_10_2_18. Since we are using 10_5_0, I expected that it would work fine but it didn't.
