[Albert Knutsson]

Dear Rivet developers,

please find attached a new set of files updated according to your 
requests, and also
our response below. We will still update CMS_2011_S8884919.
It will be send to you as soon as possible.

Cheers,
Albert

Ok, done. (See also earlier answer.)

Ok, .plot and .info updated.

Answer from author:
The ".plot" file I sent lists the cuts and also the x- and y-axis labels 
(the observable).
For more clarity, I put additionally the formula of the observable and 
copied the info from HepData and some extra info into the ".info" file. 
An update of the analysis with more integrated luminosity is foreseen.

CMS_2011_S8884919 will come later.

Discussed in earlier mails. Nothing changed.

Ok, a few more lines were added to the info files. For more info we 
refer to the publications.
