Narrative:

Cleared for ILS 36R we switched to the tower at the OM. Tower told us to turn right and reintercept the localizer. I turned right slightly instinctively till the captain and I looked and verified that we were on centerline of the ILS 36R. The captain told the tower that we were on the localizer and that we had the runway in sight. The tower controller's approach map display may have been off centered a bit. I have heard of it happening. We were cleared to land and no other events occurred.
