  7. Trigger Strategy • During initial running detector affects may affect trigger items. • High threshold menu items without PS • Be careful with TE • Plan to keep several thresholds as luminosity rises towards design luminosity. • Provide standard candles for monitoring performance. • Vary PS and drop some lower thresholds when needed.
