Various scripts to make CERN life easier, with various amounts of explanation :P
CERN Words:
xAOD: ATLAS Run 2 datasets, contain oodles of physics data, Size: ~100's of GB to TBs each
DxAOD : "Derived xAOD", made by dedicated teams for different classes of analyses, Size: 10's of GB to 100's each
MxAOD: "Mini xAOD," made by me :P , made for the largest analysis subgroup (Higgs-> gamma gamma), Size: ~100 MB to a few GB each.
EOS: CERN Mass storage solutions with large group-specific areas, where I stored the MxAODs
Grid: The CERN computing grid. Used by me to produce the large amount of MxAODs from the large DxAODs.
MC: Monte-Carlo, Simulated physics data used for analysis and comparison to data
Data: Actual physics data from the ATLAS detector
