keyword=delta P detector cutsI looked into the dips in the deltaP spectrum seen with cer cuts. At first it was thought there was a problem with the gas Cherenkov cut, but I found the dips were caused by the preshower cuts. Figure 2 shows a plot with the preshower cut, and Figure 1 shows the same run (1647) without the preshower cut. For now I have removed the preshower cut from the on-line analysis. The number of good electrons increased from 1900 to 2100 from removing this cut.
