[FeatureRequest] Change DAS strings of central samples to MiniAODv2

[reimersa]

Current situation and requested solution

In the current sample database (background and data), the samples refer to the MiniAODv1 samples. This needs to be changed to MiniAODv2 for the re-tuplization.

To be done after

• nothing, can be done at any point

To be done before

• Re-tuplize tuples using MiniAODv2 and extended content #18

Steps

• Find DAS names of all samples, exchange in database files
• Potentially need to remove or add some backgrounds.
