Reason for Change
The current set of energy bands (100-300, 300-1000, 1000-3000, 3000-10000, 10000-300000, 100-300000 MeV) divide up the data too finely, resulting in mostly upper limits in the top two bands, whereas the bottom three bands mostly show redundant information to the overall band. A proposal has been made to change to (300-1000, 1000-300000, 100-300000) MeV.
Test Procedure
Table changes and rollback procedure have been tested using the dev tables. The tasks were tested in dev with the new energy bands using data in /ASP/TestSims2.
Rollback procedure
The table changes will be implemented using the script refactorEnergyBands.py and the rollback can be performed using restoreEnergyBands.py.
