CorrectionSet (schema v2)
These are the photon ID, Pixel veto and CSEV Scale Factors (nominal, up or down) for 2016postVFP 
Ultra Legacy dataset. Each kind of scale factors, depend on the chosen working point, some other 
quantities. More information is below! Please keep in the mind that if your analysis is sensitive to
high pT photons (>500 GeV), please refer
