Data release for "Scintillator ageing of the T2K near detectors from 2010 to 2021"

The data release is associated with the paper "Scintillator ageing of the T2K near detectors from 2010 to 2021”, published in the Journal of Instrumentation and arXiv:2207.12982 [physics]. The data release contains the data points and associated fits from the paper within two root files: The file T2KNearDetector_ScintAgeing_Standard_DataRelease.root contains the data points and fits shown in the standard ageing results described in Sections 4 and 5 of the paper. The file T2KNearDetector_ScintAgeing_ECalSupplemental_DataRelease.root contains the data points and fits shown in the supplemental ageing results described in Section 6 of the paper. All data points are provided as ROOT TGraphError objects and fit as ROOT TF1 objects. A full description of the contents of each root file is provided in the README.txt.
