2
DAQ cluster finder gets

• More events with large number of primary tracks
• Fewer events with large number of global tracks

3
DAQ Cluster finder gets

• Smaller RMS distance from global track to hits
• More short tracks (more track splitting)
• Better peak for long tracks

Why? Consistent with wide distribution of
tracking cuts in tcl
