Field with the author name in github2_pull_requests index

[canasdiaz]

When looking for the author of a review in the index github2_pull_requests what field do we have to use? I read at https://github.com/chaoss/grimoirelab-elk/blob/master/schema/github2_pull_requests.csv

• author_name: Pull request author name from SortingHat profile.
• user_data_name: Pull request author name from SortingHat profile.

Can you please confirm they contain the same information
