A heat is considered raced when the Referee blows the whistle. The Chief Marshal or Referee can set the heat status to raced by using the SCM_Marshal application..

A heat is considered closed when all the race time data has been entered into the database.

Race-times can be entered by the Chief Timekeeper at the poolside by using the SCM_Timekeeper application. They can't close the heat, only the core application can do that.

After the Referee flags the heat is over the Chief Recorder does an Q&A and then closes the heat.
