[Rivet] Scaling histograms

Create a file with your histogram IDs and scale factors, something like
this:

/ATLAS_2012_I1083318/d01-x01-y01   0.555
/ATLAS_2012_I1083318/d01-x01-y02   0.555
/ATLAS_2012_I1083318/d03-x01-y01   0.555
/ATLAS_2012_I1083318/d03-x01-y02   0.555
/ATLAS_2012_I1083318/d04-x01-y01   0.555
/ATLAS_2012_I1083318/d04-x01-y02   0.555

Then run

rivet-rescale --fast -O your-scale-factor-file --multiply your-aida-file.aida

and you'll get a file called your-aida-file-rescaled.aida.

HTH,
