Training Data for Gollum in Higgs Uncertainty Challenge

This is a subset of the training data for "Gollum", Team HEPHY's submission to the FAIR Universe Higgs Uncertainty Challenge. For the full training, we used systematic variations up to 3 standard deviations. All of these can be generated from the nominal file (provided by the challenge) and the code that the challenge provided. 

Data was taken from CodeBench: https://www.codabench.org/datasets/download/b9e59d0a-4db3-4da4-b1f8-3f609d1835b2/, and systematic variations were applied according to the description https://arxiv.org/abs/2410.02867.

The files are:

• nominal.h5 is a dataset without systematic variations
• met, jes, tes in the file name indicates a variation of MET (missing energy), jet energy scale, or tau energy scale to the value that follows. For example: the file tes_0p99_jes_0p99.h5 includes events where the tau and jet energy scales were both multiplied with a factor of 0.99, corresponding to nuicances parameters with the value of -1.
• Normalization-type uncertainties are not included, as these samples can be obtained by changing the corresponding event weights. 

The file toy_mu_2.h5 is a toy dataset with true value of the signal strength mu set to 2. The detailed values of the nuisance parameters (in the format (1+alpha), see the documentation of the Challenge) are stored in a dictionary that can be found in toy_mu_2.pkl: 

import pickle

myfile = open('toy_mu_2.pkl', 'rb')
nuisances = pickle.load(myfile)
print(nuisances)
