Validation of RecHit Energies Against SimHits in HCAL

This analysis focuses on the validation of RecHit energy compared to SimHit energy within HCAL cells. It provides separate statistics for HB/HE, HO, and HF, addressing various parameters such as digis, pedestal, amplitude, and energy ratios. Key metrics include the ratio of RecHit energy to SimHit energy, along with mean and RMS values for OVAL HF, HO, and HBHE. Results indicate expected values for mean and RMS across different entries, contributing to the ongoing assessment of simulation accuracy in HCAL.

Presentation Transcript

  1. HCAL Validation • Compare RecHit energy with the energy of SimHits in the cell • Doesn't address correctness of SimHits

  2. HCAL OVAL Validation Can print out statistics, separately for HB/HE, HO, & HF: • Digis: • Pedestal • Amplitude / SimHit energy sum • ratio of max bin to previous bin • ratio of max bin to next bin • RecHits: • Ratio of RecHit energy to SimHit energy sum OVAL HF Mean: 1.01064 (expect 1) RMS: 0.0356603 (expect 0) for 803 entries OVAL HO Mean: 0.980084 (expect 1) RMS: 0.14928 (expect 0) for 2 entries OVAL HBHE Mean: 0.95699 (expect 1) RMS: 0.166958 (expect 0) for 1084 entries
