GitLab now enforces expiry dates on tokens that originally had no set expiration date. Those tokens were given an expiration date of one year later. Please review your personal access tokens, project access tokens and group access tokens to ensure you are aware of upcoming expirations.

Jonathon Mark Langford requested to merge jlangfor/HiggsDNA:dev_NNLOPSreweight into master Apr 21, 2023

Add function to event_weight_systematics.py to perform NNLOPS reweighting to ggH events
Only serves as a correction, not as a systematic uncertainty
Uses dataset_name to only reweight events with "ggH" in the name. This could be improved?
Builds linear splines from information stored in JSONs/NNLOPS_reweight.json. Correction factor depends on (truth) Higgs pt and njets, extracted from events.HTXS object
