Hi Holger,

hm, I don’t think there is fail-proof heuristic that can distinguish between a simple ratio, an efficiency, a double ratio or something even more complicated. Best thing would be to get the re-entrant histogramming going, so you can just re-run the finalize on the merged intermediate histograms. :-)

Cheers,
Chris

Hi Chris,

in that regard --- when merging scatters in general, is there a
mechanism to identify scatters that are "safe to merge"?
I.e. to identify whether you can just calculate the mean of points?

Hi,

just to say that I’ve just committed a bug fix for ATLAS_2012_I1083318 (7 TeV W+jets).

The Scatter2D containing the ratios of consecutive Njet bins was being filled suboptimally in the finalize and there was a potential for bins to be skipped in case of low statistics, which causes a problem when merging multiple yoda files.

Cheers,
Chris
