[Rivet] Question about adding an ATLAS CONF note data points for comparison plots

[Andy Buckley]

Hi Raghav,

The YODA and AIDA formats both discriminate between "histograms" and 
similar which have number-of-entries, sums of weights, etc., and 
"graph/scatter/datapoint-set" objects which are just list of x & y 
points and their errors. Reference data all has to use the latter sort, 
since the details of the histogram filling aren't recorded.

If you take a look at some of the .yoda reference data files that come 
bundled with Rivet, you'll see the syntax for the YODA Scatter2D type, 
which is the relevant thing to use. It's fine to enter the values from a 
plot grabber, although obviously there are better ways for "official" 
analysis submissions from the experiments because they have the original 
data files available.

Regarding writing the .cc analysis code, yes you will need to do this. 
We need a more specific question, though! There are some tutorials 
linked from the Rivet website via the "Documentation" link, as well as a 
quick guide under "Writing an analysis". Let us know if you need help 
with some aspect in particular.

Cheers,
Andy
