Fall 2014 Data Calibration Status
This table summarizes the status of the calibrations that have been stored in the CCDB.
Last Updated -- 17 Feb. 2015
- red - This category has not been calibrated
- yellow - Calibrations have been partially done, or done with cosmic ray or other non-photon beam data
- green - Calibrations have been done with photon beam data

Notes:
- "Base time" refers to the relative timing between different detectors.
- The fADC and TDC categories refer to per-channel calibrations.
- The high-level reconstruction objects are the final inputs to a physics analysis. The low-level reconstruction objects are whatever objects are built from the calibrated hits and used to build the high-level objects.

Performance
Values obtained from data are shown in blue.
| Detector | Timing resolution | Energy Resolution | Spatial Resolution | Efficiency |
|---|---|---|---|---|
| BCAL | 1.8 ns / 70 ps/sqrt(E) | ~19 MeV (pi0 mass); 20 MeV @ E=140 MeV/ 5.4%/sqrt(E) + 2.3% | 6 cm (ADC), 35 cm (TDC) [z] / ~8 mrad (trans.); 1.1 cm/sqrt(E) [z] | |
| CDC | / | / | ~150/250 um (far/close to wire) / ~200 um | |
| FCAL | 3.2 ns / ~0.4 ns | ~25 MeV (pi0 mass); ~8% (beam e- E/p) / 5.6%/sqrt(E) + 3.5% | / 6.4 mm/sqrt(E) | |
