| Summary | 0000383: mcsmear BCAL: Simulate ADC timing algorithm | ||||
| Description | Currently in mcsmear, the times for DBCALHit objects (i.e. ADC hits) are calculated as threshold crossing times, then smeared with 4 ns/sqrt(12) time resolution. In reality, the ADC will not report a threshold crossing timing, but use a more sophisticated algorithm to determine the time. In addition the time resolution may be better than 4 ns/sqrt(12). The fact that we simulate this as a threshold crossing time means that we need to take an extraneous step of timewalk correction when reconstructing simulated data (that is, we need to do timewalk corrections to the ADC hits in addition to the TDC hits). | ||||
