[Rivet] question about run-averaged histograms

[Raghav Kunnawalkam Elayavalli]

Hi Andy,

Ahh yeah sorry I mean I wanted to find the average of a histogram at the end of the run and fill that average and RMS to another histogram. Is that doable?

Hi Raghav,

Can you explain in more detail what you want to do? You want to average
histograms over several independent runs? That would usually happen
*outside* Rivet -- the finalize() method is called at the end of each
independent run, not as a way of merging those runs together.

The yodamerge script might be what you are looking for, at least as an
example.

Andy
