Robert Easton: The obituary of actor and dialect coach Robert Easton in the Dec. 22 LATExtra section incorrectly identified Heather Woodruff Perry as Easton's daughter. She has advised that she was not officially adopted.
Mercury emissions: In the Dec. 22 Section A, an article about a new Environmental Protection Agency rule that would reduce mercury emissions from power plants misstated the stricter emission limit as 1.2 pounds of mercury per million BTUs of energy produced. In fact, it is per trillion BTUs of energy produced. An article in the Dec. 16 LATExtra section included the same error.
