Support for detector efficiency corrections for 7TeV CMS data

We are looking at CMS open data located at CERN Open Data Portal to understand acceptance effect.

Your data are published here

However without having the proper pt/eta dependent efficiency, it is not possible to get the final physics results.

1)Could you pass us the charged particle tracking efficiency for 7TeV pp data in pt and eta?
2)Or point us the corresponding MC open data?

First option is really desirable for external users and easy to provide since you have used it to correct the results already. Maybe because of the policy, first option is not possible but I should seek for the correct procedures.
