[Rivet] Update & new analysis

[Gavin Hesketh]

Hello,
Just to let you know one D0 Z+jet analysis has been updated in Hepdata:
http://hepdata.cedar.ac.uk/view/irn7863608/plain.txt

previously the Z+jet distributions were only available as absolute cross 
sections, now they are also available normalised to the Z cross section. 
This should make them much more useful for comparison to LO event 
generators! Hopefully this can be propagated to the rivet analysis? I 
could maybe look at it if needed, but it's been a while since I tried 
any rivet coding.

Also, there is a recent very precise measurement of a Z pT-like variable 
from D0:
http://arxiv.org/abs/1010.0262
will this be included in a future release?

thanks,
	Gavin
